see if you can keep that speed with cas 7 ram and NB is very low?

great clock and temps though

 

[Flyordie]

Ok, bout to post a thread in the FS/FT section which will contain my X4 920 and maybe some other goodies...

Figured I would give you guys headsup before it goes gold.

my ram won't do it. It just not that tight runing but 1666 is decent, at these speeds ram timing makes very little difference in the real world, lots of testing on that subject and lots of reviews report the same thing.

What vDimm are you running? And can they at least do CAS8? CAS 9 at that speed actually isn't all that great. That's like DDR2 running CAS5 at 925Mhz. I'd rather try for 1333Mhz CAS6 if I were you.

 

[eidairaman1]

I think DDR3 Timings are getting closer to DDR Timings than DDR2 ever did.

DDR2 far surpassed DDR a long time ago. Take 1200Mhz CAS5 DDR2. DDR would've had to be able to hit 600Mhz at CAS2.5 to keep up. Not gonna happen for 24/7 use.

past drr3 1400 timing makes very little real world difference, these new chips, I7 included just cannot use all the bandwith. These are just average ddr3 Giskill nothing special.

and this is a bit better, not bad for a 80.00 motherboard.

You are absolutely correct about the bandwidth, but you are forgetting latency. 1333 cas6 would be faster overall.

Yes but this ram was 84.00 and faster than what ? Ram timing is the least important part of these new systems might make a 3 percent difference if that. I can run those speeds at ddr3 1333 7 cas no problem. Also with these quad 4.0ghz with bus at 250 is no small thing.

3% is still 3%, and 1333 at a tight timing would be easier on the IMC. I'm not knocking your ram, I'm just saying 1333 CAS6 would be better if you can do it.

I know your not knocking it, how can ya for 84.00. It was a steal, but ram isn't important to me really. Also this is a Vista 64 overclock, with a Phenom II x4, with 250 bus speed, on a 80.00 motherboard, using a 84.00 ram. I think it's okay not stellar, but you get what you pay for, and I payed very little for this level of performance. However, even after all that it's fast as hell. Also this motherboard doesn't like a high northbridge speeds it gets goofy around 2500.

This is my ram but I got it on sale for about 20.00 less http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277&cm_re=gskill-_-20-231-277-_-Product

real fast cas 7 run and my xmp ram rating

ram may make very little difference in real world i'll take that however your NB at 2250mhz is not as unnoticed real world thats linked in with your L3 cache and all that other good stuff and phenom's do use that L3 in encoding and all your other daily tasks. evven if you have to loose some ram speed pick up the NB speed its what sets apart benchmarks not the ram.

I meant tech in general, simpler name would be PC store workers. Sorry if confused you or something.



Yeah, i know.




Dude, i have bought Phenom II 955 & guess what revision is it ? A f***ing C2 !!! Now for the good part : i just hit the 3.6GHz without ever slightly overvolting it (look into my Sys Specs). I saw the default Core voltage was 1.360v in CPU-Z, recalled that when set to AUTO in BIOS it is 1.35v, changed it in BIOS to the said value & throughout entire small multiplier increases never touched it. 'Course i wouldn't reach your frequency on air, but atleast i see a great potential to hit something like 4.0GHz. And thanx for reminding me you have car rad to cool down your CPU !!! jk Take care dude.

While @ it : need help in next subject - 2x120mm 19dBa each (20dBa each tops) 50CFM fans ? Do not feel like waking up neighbors with jet take-off sound of fans. Noise is an issue in my neighborhood.

therefore i told you to get a c3 965, because they cant be c2
3.6 ghz on stock volts are decent, for a stock cooler. I admit mine never saw an air cooler in all its life, only for 5 minutes, as i tested if its DOA as it arrived
regarding fans: buy enermay magma. theyre quiet and powerful. and have double the air pressure of an ordinary fan.

lol, I wouldn't exactly be upset that you got a C2 model. Mine is a C2 as well and is awesome on air cooling...might be even better on water cooling. I've already hit 4Ghz on a budget $80 motherboard. If I'm totally honest, I'm actually afraid to get a C3 for fear that it might not be able to do the same things my C2 can do lol.

Amen, northbridge makes all the difference in the world. I'm still big on ram timings since they're still very important especially in reference to stress on the IMC. 1333Mhz cas6 is fantasticly responsive for daily usage so if you can get it then absolutely go for it. 1600Mhz cas7 just isn't the same, but if that's the best that you can get (try 1333Mhz cas6 first of course) then make sure that you can get your northbridge speed up high enough to match.

I keep my systems memory read and L3 read speed as close to equal as possible, if any one has to be marginally higher then the L3 is the one...but marginally higher. It produces a fantastic responsiveness in the system, and isn't that hard to get.

1333Mhz cas6 when paired with 2250Mhz Northbridge is a thing of beauty! Make sure that you keep the cpu speed in mind when looking for those goals. If your cpu speed is too low you'll have to run a much higher northbridge speed in order to make the memory and L3 read match...but then you're still out of whack because the system is lopsided with too high a northbridge speed and too low a cpu speed.

im addicted to NB speed! and to responsiveness! nothing will be as snappy on AMD as ddr3 1250+ with cas 5, and really high NB speeds, like 2600+ !!
I LOVE IT!

Freindly reminder...

Little did I realize, I never installed my SB driver during my last O/S install and took a couple days to remember. AMD doesn't make these easy to find, but if you have an AMD chipset and find yourself reinstalling your O/S, always remember to install these:

http://game.amd.com/us-en/drivers_catalyst.aspx

Select: Motherboard/Integrated Video Drivers --> Individual Drivers (Motherboard/Chipset) [select your O/S] --> South Bridge Driver.

You can also find your AHCI and RAID drivers in there.

Good one, thanks bro. I'll be doing my re install of W7 shortly, soon as I receive my SSD.

i still gotta wait to install win7 jj gave me a key or 2 but arg doing the wallpaper for him is harder then expected so i cant reinstall yet -____-

Can you guys give me some northbridge speeds and htt, that I should shoot for, my ram is lower end, but northbridge and htt can be raised. I can do 3.7 ghz at default with bothN/B / HTT at 2500 and use cas 8 at ddr3 1600 or cas 7 at ddr3 1333. I'm sure I can go higher on the core but messing with the HTT/ NB for now.

See what Kei said, add me to it+better for me now to wait for Thuban (plus that GF100 DX11 card, i guess) & you'll know how happy i'm with current situation, Wafer. To get these clocks out of rev. C2 CPU - i say, IT'S ALIVE !!!!!! This 3.6GHz is probably 24/7 (or something like that) gaming/web browsing/movie watching clock, til i get my hands on TRUE.

Enermay ? You mean Enermax maybe ? I'll check for it. Thanx. How much CFM & dBa are the best ones ? What about Thermalright's own or Scythe's S-Flex ? Thanx again.

Any insight on hwo I can improve this?

CL7 Isn't memtest stable, even up to 1.8v, and chip won't unlock.

lower the divider maybe, some procs have a fairly weak IMC, and dont like NB clocking and Ram Timing at that Ram Speed
it helped very good with mine!

IF i were you, Xanlord, i would have ripped my Hair out Or bought me some better cooler,upon buying the Phenom.
sry for that Typo, i really meant Enermax. i really dont care about fan data, its bullshit. i hold my hand in front of it, to feel how good a fan is.
the Enermax are the Best, regarding that Test. they get REALLY cool. and look stylish too,also their blades are detachable ;-)

 

[JrRacinFan]

Will report back with a mem bench screenshot on the 1066 divider.

EDIT:

Was able to change a few timings too. Notice L1 latency went up and L3 latency dropped. Hmmmm....

@jr have you tried to see if your wifes board will unlock your chip correctly?

HTT link is unimportant most chips can do over 3ghz HT link no issues shoot for a NB around 2800mhz and the ram at 1600 cas8 isn't to bad i would push that

Nah and it's too much of a pain to try with it now being in a lanbox. Not worth the hassle.
