AMD 955 Black Edition Phenom II

at 3.2ghz after 10mins of Prime95 Small FFTs on all 4 cores:

Core: 50-51c (fluctuates every couple of mins)
CPU: 48c
GPU: 49c
HDD: 28c
MB: 42c



at 3.7ghz after 10mins of Prime95 Small FFTs on all 4 cores:

Core: 52c (fluctuates every couple of mins)
CPU: 50c
GPU: 49c
HDD: 28c
MB: 42c


Should I be happy or should I be reinstalling my CoolerMaster V8?

I'm sorry for my confusing post

In short I am saying that I get same temperatures at 3200mhz and at 3700mhz

Anyhow since then I updated my BIOS as well to latest version. Seems that my VCORE was set higher with supplied BIOS!

Using Prime95 again with Small FFTs:

My new results are:

For 3200mhz (stock): Idle - ~36c Prime95 for 5min load - ~45c

For 3712mhz (18x206): Idle - ~39c Prime95 for 5min load - ~52c



I guess nothing will stress the CPU as much as a torture from Prime95 game or application wise meaning I'm safe I suppose

you really should do more than 5min load, go for something like, 8hrs to figure out max temp

Bah won't let me edit !

Anyhow,

I just started a small FFT test and put SpeedFan on my autoconfig to see where it will stabilize. I made sure the fans will go 100% if it goes over 55c.


I'll let you know in approx 10-12 hours on how it went

Thanks for your input so far !

NB voltage is set to stock/auto I didn't mess with it.

CPU voltage is reported as 1.392v in CPU-Z and SpeedFan but Asus TurboV says it's 1.45v

I did 18x206 and set ram voltage to 1.9v

I've managed to go up to 4ghz with this voltage but it's not very stable. I'm kind of worried to push voltage further since I don't know the 955 Black Edition's safe VCORE limit (meaning, not to burn my motherboard / CPU etc.).

Problem is I had an ASUS M3N and a 955BE... It burned up on me due to VCORE tweaking on my side. I had a 600W PSU at the time. Nothing else got harmed just motherboard + CPU.


Anyhow, I got an ASUS M4N72-E now and another 955BE and also the OCZ Fatal1ty 700W SLI PSU just to make sure everything gets enough power.

I'm also running at 8GB 800mhz ram and a GTS250 1GB...Which I'm going to SLI soon

I'm wondering if the performance gain from 3.7ghz to 4ghz is worth the effort/risk tho ? I see you're at 4ghz so maybe you can enlighten me ?

Well 2 hours into Prime95 torture and I'm at 48c in CPU sensor of motherboard and 50c at the Core sensor at 3.7ghz

I pretty much have the best cable management I can here. Strong intake fan in front 250mm and strong exhaust of 120mm... Coolermaster V8 on CPU...Heatsinks on all four sticks of RAM and my sidepanel is meshed so airflow is indeed good.

All my cables were passed on right side of the case and streamlined, lock-tied and wrapped in UV piping for effect and management

Anyhow I'll stick to 3.7ghz for now since I can keep it running with fairly silent fan operation at 48-50c when gaming and SLI my GTS250

Also I made another post for my HDD setup i'd be glad if you dropped by and helped there


Thanks for your help guys!

Do you have a link to your new thread?

It looks like that thread was posted on Tom's/UK's website.....

Anyways your hard drive will not bottleneck you 250's in SLI... I used to have dual 250's in SLi with a single 640Gb drive and it was stupid fast...i would even get high frames on Crysis with some eye-candy... You can get an SSD if you want but don't expect your games to run any faster.. An SSD can speed up your boot and loading times but that is about it..... As far as Raid0 goes I have dual 640's in Raid0 and they are hella fast trust me... I only had to spend 150.00$ for both with free shipping...For dual drives that run faster than a stock raptor I cannot be happier...

You really need 4TB's of storage?

WoW... that is quite a library.. I have a little over 1TB and I have only used 15% of disk space....Well I am using a 780a Sli chipset and as far as the raid array goes i see no flaws, don't really know anything about the 750a since I have never worked with one....Should be more or less the same...

Hey guys, just a quick query, what kinda scores are average for the 955 on 3d Mark Vantage, im gettin 12600 for the cpu with stock coolin o.c. to 3.6.

oh n also, i struggle to get stability over 3.7Ghz, is this normal or do u recon ma overclockin methods are screwed?

I reach 3.7 with 18x206 on stock voltage, i can ease the voltage up and had a proper play yesterday, but i just got so unstable when i started messing with the v. I'm gona give 18.5 a go in a bit and ease the voltage untill its stable, the stock cooler looks pretty good, ma load temp is around 56c so i wasn't gona buy after market coolin, but been considering it since i cant get 4ghz which is ma target.

Im also trying to drop the latency on ma RAM, i read that it could go to 8/8/8/20 with ease (from 9/9/9/24), but no joy for me!!

Give it 1.38/1.39vcore / 1.38v on the NB
Multi @ x18 and raise the bus to 210 (later on you can keep raising the bus to overclock you ram a bit)

If found that Turbov and AMDOverdrive dont show whats been changed in my BIOS, i can only assume that you have to set all bios to auto and only change settings with the software. I just use CUP-z and change everything in the BIOS, much more reliable.

ok, ive set my NBv to 1.38 and ran 3dmark Vantage, got the best score yet and it ran silk smooth, cheers for your help, i recon i can keep my current system now until the 5870's reduce in price.

Cheers

i get 13600 at stock (3.2 GHz)

For me at 1.44-1.46 I can keep 3.77 stable.

but I can't go under that in volts or I crash in windows. Even at 3.7 I crash.

My NB voltage is stock. Should I try to raise it so I can push it further?

Even with the NB voltage increase I still crash at 3.8

I set the multiplier to x19 and 200 fsb and its at 3.8 no crash. Thanks. Doubt I could push it any further though.

just remember that sometimes that extra 200mhz ain't worth the risk / burned CPU

3.8 @ 1.44v

38-41C idle
51-54 load


Ran Crysis for about 3-4 hours then Prime95 for 15min to max it out. Seems fine and I'm not into running prime for 8 hours.

I have an Asus M3A78-CM theres only 3 options for the voltage. +50mv, +100mv, and +150mv. 150 is 1.44 So i dont know how to change it.

edit:

just dled AMD overdrive and its saying 1.3v but CPU-Z says 1.44v???

How would I go about doing that? Can you save screen shots while in the bios?

Alright I appreciate it. I don't have a camera haha.
