2G Kingston KVR good?

[_33]

Hi,

I have read a lot about the KVR400X64C3AK2/2G which is Kingston's Value kit for 2GB of memory. I read it's very compliant to the NF4 and AMD cpus. Even that it does 3-3-3 out of the box and can be overclocked to 444mhz at 2.5-3-3 timings. Anyone has that kit and can post performance scores? Sandra / Everest / 3Dmark / superPI ...

THIS MEMORY

Thank you!

I have two 512MB Kingston Valueram modules and they are very quick and reliable for the price. They work well with my NF3 and AMD64, other than my mobo's memory speed problem I've had nothing to worry about.

But I'm talking about the 2x1GB kit. They are totally different, because I have the KVR 2x512MB and I heard the 2x1GB kit is much much improved in overclocking and tweaking capabilities.

Even, I think the chips on the Mushkin HP3200 2-3-2-6 2x1GB which are Infineon (rated 3-3-3) are the same used on the KVR 2x1GB kit.

EDIT: Was wrong, the KVR 2GB kit uses even better chips, the Samsung UCCC!!! Someone help!

 

[Jimmy 2004]

Sorry, I thought they'd be quite similar. My mistake.

 

[_33]

Well.....

Seems I equiped my PC with 2 gigs of Kingston KVR (value ram!). Ok, before we get all excited and laugh about the value ram and what people think about what are the performances of value ram. Let me post some figures here, after just a few hours of tweaking. I can tell you guys this ram is much much faster than the 1 gig of KVR I had before. They are dated week 18 of 2006, and very compliant with my DFI. Of course it won't overclock much... But for the price, it's pretty damn fast memory, and specially for 1 gig per stick!!! I wasn't expecting such tight latencies, and 1T overclocking is still nice.

Update on performance

Well, here's something I was able to do with the 2Gig DDR1 Kingston KVR kit. The problem thoe is I had to bump the voltage to 2.8 and I have no heatsink for those sticks, so they are highly unstable at DDR466. Bu I was able to take those snapshots, post them here while enjoying this bandwidth, no errors of course! So that's at DDR466 and only cas 3-3-3-8 but all the rest are tight timings and very tweaked for the least errors at higher clocks.See how close my bandwidth is to these 2GB PC8000 DDR2 sticks. And, be even in bandwidth (but much better latencies on my part) compared to these Corsair XMS DDR2 PC8500 1GB sticks (rated 10 out of 10). I'm not through with overclocking these, next I'll try to put cas 3.5 and cas 4 see how much more I can raise them. 7gb/s in Sandra would be sweet! Yet, I will never be able to beat these serious OCZ DDR2 sticks!!!

I'd have to say thoe that staying DDR1 for now is a wize choice, probably until DDR3 shows up.

EDIT: CAS 3.5 and CAS 4 not possible. Won't even boot to bios. I don't know how that can be. Sadly I was counting on that to push the mhz, but eh! Last thing I can try is more volts, but need some copper plates to help the ram sticks.

Hello I am new to OC'in but a member on our site, HKS help me out.
i also have kingston valve ram and he said he does not know how it is going so fast. Mine is running right now at 240mhz and stable, pass 3dmark05 and plays BF2 and GTR fine. temps are 28c idle and 48c loaded.
i am running a AMD 64 3800+ but with the OC it is running faster than a 4800+
here is my ram
Kingston Valve Ram
PC3200 2x1g sticks
@ 200 MHz 3.0-3-3-8 (CL-RCD-RP-RAS)
Serial Number Modual 1 = 73387B85h
Serial Number Modual 2 = 73387A85h
Also Added Heat sinks to the ram sticks.
and i got a BFG nvidia 7600GT OC

we are planning on going higher in speeds but i wanted to get a better cpu cooler it was stock.

for all the info and pics hope over to our site and take a peek. easier than reposting pics.

Yes those sticks will overclock like mad for value ram. It's specially because of the chips used on these sticks. But in no way it should be looked at as high end. Still, I looked at your sisoft sandra bandwidth, and seems bad. It says you are running your ram in 2T mode. I bet that if you run them in 1T mode, you might not hit 240mhz, or might be unstable. In 1T I am unstable at 234mhz with not heat spreaders on ram. Anyway, my bandwidth is way past 6GB/s in Sandra, and your says 4.8GB/s. Definately, something wrong in your settings. Could you put your ram settings here so I can see what's wrong? Maybe a snapshot from A64tweaker or something like that...

 

[DGuy]

what sandra version are you running because i found in 2007 version your scores are lower than in 2005.

 

[Jimmy 2004]

You mean bandwidth scores are lower? They shouldn't be because they are measured in set units, it isn't like 3Dmark which becomes harder with the new versions.

 

[DGuy]

no my scores in sandra 2007 are lower than in 2005.. my cpu only get 18000 dry or something in 2007 but in 2005 i get 20000 dry. for cpu test. my memory in 2005 will get close to 6000, it was 5900 or something.

i am stabe a 2t at 240mhz but 1t is not. just tried.

but what are the setting you are running your ram at??

The CPU score in 2007 has been reajusted because of miscalculation in earlier Sandra, but the memmory bandwidth I have tested with 2005 and 2007 and they give the same results at 100MB more or less difference. The results you got from sandra is one thing, you might want to try Everest see what you get there. I get 7GB/s on Everest.

 

[DGuy]

ok here are a couple of pics of the ram

i am new to the OC and we just started off easy by moving the FSB and volts. i am stable right now at 240mhz but thats in 2t.. if 1t will be faster at a lower speed i can change the ratio for the cpu and ram and get more out of the cpu still.

At 1T command rate, try 200mhz FSB and leave it stable, then raise it to around 217mhz (DDR433) in 1T 3-3-3-8. The next step is go in A64tweaker and take a snapshot of that and I'll give you a snapshot of mine and we'll see how different our sticks are see if you can achieve a nice bandwidth (6GB in sandra bare minimum). I also run at 2.7v btw. 2.8v preferred for stability in frequencies above 230mhz and above in 1T mode. The problem btw, with that software (Easytune 5) is that you're runnign 1:1 ratio fsb/ram speed. The Athlons are capable of much much more flexibility than that!!!

Dump that fancy looking program and replace that with a more flexible tool called SYSTOOL.

Have you tried bumping up your voltage yet? That might help.

 

[DGuy]

i just used easytune so while i was doing it i could talk to the guy helping me on teamspeak. once we found it would work ok at 240mhz i went in the bios and set it there. I'll give that a go tonight after work.

as for the voltages. cpu stock was 1.35 and i moved it up to 1.4 and the ram was 2.6 stock and it was moved up to 2.7.

but it i get higher bandwidth with it at 1t does that mean it is running faster?

 

[Jimmy 2004]

1T is faster in just about all cases.

The most important in memory is not the frequency, it's efficiency (DDR2 proved it)! 1T setting is the first step. 200mhz 1T will give you better performance than what you actually have. Please have confidence, I went through the same things as you before.

 

[DGuy]

ok well i tweak it last night got it to go into 1t but i could not got 217mhz. computer would not start. so i set my cpu to 250mhz and ram to 228mhz booted great. and passed all tests.

here is the A65Tweaker screen shot you wanted don't know if it is right

and hear are the resaults for the specs above

 

[_33]

So here are my memory settings. Here I circled the areas of difference between your ram and mine, except the MEM CLK 2 and MEM CLK 3 which I think must be an error since you have 2 sticks and should be disabled.

The reason you couldn't clock to something like 217mhz ram is because your Read Preamble and Async Latency is too tight. So at lower clock it wouldn't get to those short timings and so would lock the system. Those are not influencing performance, so they must be let loose.

Row Cycle Time (Trc) as you can see I cut that one short. The minimum is either 7 or 8 depending on frequency of ram. You could have to raise it to 9 at over 240mhz.

Row Refresh Cycle Time (Trfc). 13 is a good compromise. 13 is good up to 225-230 mhz, past that you need 14. Past 240mhz, you'll need that at 15.

RAS to RAS Delay (Trrd) can be set to 0 as the memory makes it's own delay on that one so the system doesn't really have to figure this out.

Write Recovery Time (Twr) at 2 make a little difference in performance, compared to 3. It's a nice one to set.

Write to Read Delay Time (Twtr) at 1 is nice, again you really get better latencies with this lowered to 1.

Read to Write Delay Time (Trtw) at 2 gives some nice performance gain compared to the default value of 4.

Refresh Rate (Tref) is set to 100mhz at 7.8us because it giv es better stability overall

DQS Strobe Timing: The 2 values in there is basically setting the DQS to allign memory cycle in a way that you get less fails from your memory. My current settings for that one are quite standard for overclocking.

Dynamic Idle Cycle Counter: Said to bring better stability when enabled, and it does.

For good measure, I want to share this nice program I found called A64Info v0.60. It's a little better than A64Tweaker and has more functionality, less bugs.

 

[DGuy]

ok so if i change these numbers. should i increase my speed and sability?

Thanks for your help by the way. i am new and all though i know where the numbers are and know how to change them i have no idea what the out come would be. i'll try to set mine up like yours and see what happens.

I absolutely don't understand what you mean!

Try it, break a leg. To test stability, run several passes of MEMTEST86+, specially cycles 6,7 and 8. If you get errors, it means your memory is unstable. Best is to let it run all night when you feel coàmfortable with your tweaking. If in the morning you have errors that showed up during your all night test, then the settings are too demanding for your ram and so you will need to slack and rework them properly. Believe me, I spent some hours testing these values for my 2gig KVR kit. They are rock solid for up to DDR440, then I have to slack some value and/or up voltage a bit. The only way to find out is to play around.

 

[DGuy]

ok with your setting my computer will run and i can pass the benchmark in sandra. but when i run 3dmark05 there is some issues. it runs it but my video is jumpy. running games are ok but when i use fraps to record it get jumpy like 3dmark.
so i set my ram to auto just to see and everything smoothed out no jumping at all.

I am currently running 250mhz cpu and 228mhz ram at a command rate of 1T but auto settings.

If you're not willing to work your own settings to tighten up the ram and get the best performance out of them, then my efforts are in vein. The probem also, is that I run my ram settings at DDR433 (217mhz). So obviously you have to do some slacking or else you get memory errors and possibly hangs.

 

[DGuy]

well sorry. I don;t know much about overclocking. i know a little but as for what every setting for the memory does and how it will affect everything i don't know. I got it to smooth out with your setting but i am now at 236mhz.

again thanks for your help.

is there a site that tell you hat eash does and how it will affect your system if you change? or is it more trial and error?

And one other thing it say my HyperTransport Clock is at 1040 MHz i heard it is not sappost to be over 1000mhz is this true or shjould i be turning something down to get it below
