Got curious to see what kinda latency 1700Mhz 7-7-6 1T would get me. Just ridiculousness...I love it! I'm pretty sure I could find a better setting still, but this was the first one that popped into my mind before heading off to bed.

Kei

Oh, that's just lovely!!!

 

[Kei]

whats your last latency value? there is usually 4 before the Command Timing?

That run was done at 1700Mhz 7-7-6-20-27 1T

Have a look at what Kei wrote HERE.
Most informative.

As for NB.. you can OC it, without OCing the CPU, but it depends on your mobo. Also, you'd have to increase the voltage slightly.. Pretty much the same rules as for anything OC-wise apply here as well.

Try not to go over 1.3v too much, without some hefty cooling though. From what I've read so far, more than 1.375v might actually cause damage. Chances are, that you'll find a limit of what's a decent speed for the NB, long before you get into dangerous voltage territory anyways

I'm sure the more experienced OCers here can point you in the right direction a little better than I can

EDIT: I run mine at 2800 @ 1.25v

Thank you, couldn't have said it better myself.

Oh, that's just lovely!!!

I know right! It was so fast I think I can confirm lightheaded feelings when running it from the speed lag my brain had trying to comprehend it lol.

I'm gonna try a few more configurations to see the differences...cas6 is usually the faster configuration in my experience versus cas8 so I think the next best setting might be 1465Mhz cas6 1T instead of 1768Mhz cas8 1T

More latency runs...

Did two more Everest runs to compare overall latency and bandwidth. I think that the fastest configuration of the three so far would be the 1465Mhz despite the numbers being slightly down in comparison to the first run. In my testing so far it seems that cas6 has light speed performance, and the only thing to touch it would be cas7 at an enormous Mhz which is unlikely anyway.

Either way all of the three configurations are jaw dropping performances.

Who in here has a PII 550 dual core? I'm curious to hear your results so far, I've built a system with one but didn't do much overclocking (not the purpose of that system) so I wanna know what you guys have done with it.

I don't care about the unlocking part of the deal (though that system did unlock, I didn't leave it set running that way), just the heat, overclocking, and speed part of it all.

Man, I'm dying to get some good RAM. I have the capacity, but it's only DDR3 1066 Here is my SPD table. How much voltage you think I should run on these for higher clocks? I am running DDR3-1333 right now at 1.65v BIOS, 162v windows. I am used to my i7 where going over 1.65v can damage the CPU. The most I ever did was 1.75v which oddly enough was 1.68v in windows. That was with the Intel setup.

I'm thinking the RAM can probably take like 1.8v or so as long as they don't get too hot to the touch, right?

What's the stock voltage for those modules? I know the SPD says 1.5v but all of them say that anyway...if your modules are rated stock for 1.65v then I'd say 1.8v isn't out of the question at all. If they're only rated for 1.5v then I would be careful going to 1.8v without some sort of cooling fan for the ram.

Above all....I say just buy new ram. You've got good speed, but your timings are super loose in comparison to mine (1333Mhz 6-6-5-17-22 1T @ 1.50v lowest volts motherboard has)

I bought the 1866Mhz stuff just so that I could run it at either 1333Mhz or 1600Mhz with tight timings with as little volts as possible. I wish my board could go lower than 1.50v but either way that's where I'm sitting, and have no problems with tight timings at all. My ram is rated for 1.65v stock and most I've ever tried is 1.70v though that was just for a test, and I HIGHLY doubt I actually needed it...just wanted to make 100% sure I didn't run into a ram error is all.

If you keep that ram (nothing wrong with that of course) then just bump the Northbridge up to compensate for the speed difference and it'll still be wicked fast.

Very nice Kei. Good to see you get that kind of performance out of your Ripjaws. I had a set a couple of months ago that just sucked. However, they may have just not liked the Intel boards I was trying to run them on.

Well at 1.65v they are just a tad warm with no cooling, the case has pretty good airflow since I rotated the HDD cage. However, I have two RAM coolers here at home to choose from. A Corsair and a OCz. I will get some RAM, I will try to push it a bit higher and see what's up. I think this RAM is however rated at 1.5v since it's only DDR3-1066. They used to be CDAWALL's sticks, he got them to clock pretty far with about 1.9v or something. I'll just keep an eye on them for the temps, if they die they die, I'll just have to get some good RAM

I may just bite the bullet and grab some Corsair

Thank GOD for a copy of a copy! Now I have a reciept for the board so looks like I'll try to make the exchange tomorrow. Don't feel like taking a shower, warming the engine, taking the chassis apart again, then taking mom out, pick up zee woman, return board, come home and pray it all worked out lol.

Tomorrow it is as long as they exhange it.

Kei

 

[brandonwh64]

i tried KEIs guide on the ACC and i cannot get anything stable after 3.9ghz i can run EVERYTHING on auto and just move the multi to 19x and the HT to 205 and get 3.9ghz and its rock solid! (6 hours linx and prime95) but as soon as it hits 4.0ghz its like it say

and BSOD!

Cool man, as long as you do it. I just tried my same stable settings of 3725 MHz and default voltage, but instead at 3825 MHz and they failed while I was fapping

I raised one notch in AOD but it didn't seem to change voltage so it still failed. I gave it another one and it is now at 1.408v. I'll give that a shot and see how that goes. Temps were at 48-49ºc.

Kei, guys? Where are you'll today?

Anyways, I dropped my RAM divider to 1066 and guess what? Rig is rockin' stability now!

3825 MHz would not even pass a minute of Linx before. I would need to go from 1.392v to 1.424v for it to do 5 minutes of LinX. Such a high jump in vcore and still hardly a difference? Well sure helped, but that's not what the rig was asking for! Dropped RAM and it passed LinX for 15 minutes at 3825 MHz 1.392v Now I'm on to something. Once I get CPU where I want it to be, I can always play with the RAM then.

One thing though, I changed the orientation of the CPU cooler from blowing towards the back of the case, to blowing towards the top. Went from vertical to horizontal. I applied new paste and unless the paste needs to cure a bit the temps increased a few degrees, about 4-5ºc. What I might just do is put it back to vertical how it was before and instead of having the fan PUSH, I'll have it PULL. This way It'll be on the other side of the cooler and I can put my OCZ RAM cooler on. With the fan pushing through the cooler it covers almost all my RAM slots , therefore not allowing me to use a cooler on it.

Stay tuned for more...

Ok, so I tested from 3.8 GHz to 3.9 GHz. Took a bump in vcore from 1.392v to 1.424v. So far so good with LinX, I'll leave the setup crunching the rest of the way. I'll try for 4Ghz stable tomorrow.

 

[Assassin48]

thats a real good chip you got there

 

[Chicken Patty]

thats a real good chip you got there

Thank you sir

I tried 4.0 GHz @ 1.440v, lasted about 1.5 minutes in LinX. I'll call it a day for now. I will go with the Corsair H50 very soon. When I do I should be able to 4GHz @ about 1.46-1.48v I think.

 

[jjFarking]

Did a quick membench as well.

NB @ 2800 (1.3v - but could probably run a little lower. Wanted to make sure it was 100% stable, no matter what)
CPU @ 3700 (18.5x @ 1.43v)
RAM @ 1333 (7-7-7-19-5-27 @ 1.74v)

I know I can push it a little harder, but I prefer absolute stability

That's not bad. Mine are horrible since I have NB still @ stock clocks and I have my RAM running at DDR3-1066

 

[jjFarking]

I think you can run your RAM at 6-6-6-20-24 with a small voltage increase, using the same speed.
As a rule-of-thumb, memory timings of the next speed down, can be applied at the next speed up, with a voltage increase.
Not always, of course, but usually.
Try that and if it's stable enough (I use IntelBurnTest @ 1920mb x 5 runs, logged), then go back and look at increasing your NB (try 2600MHz @ 1.25v/1.3v, if all OK, try 2800MHz @ same voltage).
You've got better cooling than me, so that shouldn't be a problem

Well I was trying to find a everyday clock for the CPU that's why the rest is untouched. Now that I have, I will try my NB next, then the RAM. I'll be doing some tweaking with the NB tomorrow

I'd actually try the RAM first, as it's better to troubleshoot any stability issues

Good luck, whichever way you go though!

hahaha.... your name made me laugh cause i thought it said fartking.

sorry if i made you mad.

good day

Updated - with CPU now running at 3800MHz; the rest is the same

Some background services were running during the benchmark, so it should read a little better than it does here.
Couldn't be bothered fine-tuning those. Besides, in real world applications/use, these are enabled anyway, so it might actually be a fairer indication
