Hi guys, great site and forums, my first post :D 

So!

I acquired one of these and coupled with a CoolerMaster V8 and MX2 thermal compound when viewing webpages/doing office work my PC idles at around 40c-43c...

(Ambient temperature is around 22-24c by the way)

This is at stock voltage and clocking (3200mhz)
CMV8 fan spinning at 2000rpm... I also have a Scythe Kama Flex fan capable of 87cfm at full speed... (also 2000rpm)

It's quite noisey at this speeds but aren't my temperatures kind of high ? What do you think ?

Info taken from SpeedFan

Full details:
HDD temp 27c
MB temp 41c
GPU temp 49c
CPU temp 41c
Core temp 43c


Now, I just switched it to Turbo mode (3.7ghz) and gonna let it idle for 10 mins...

Full details after 10mins @ 3712mhz

HDD temp 28c
MB temp 42cc
GPU temp 48c
CPU temp 41c
Core temp 43c


Now considering the overclock shouldn't it go lower?
Also if it can sustain these temperatures on 3.7ghz shouldn't it go lower at 3.2 ?

I'm kind of buffled here :D 

Do you find these temperatures good or do you think there's something wrong here ?

Thanks !
(I'll run 20 mins of Prime95 in both modes and let you know in a subsequent post!)



Also want to add my case is an Apluscase El Diablo (without the sidepanel fan)
For those unfamiliar with it -> Here it is


September 8, 2009 4:56:21 PM

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? :D

Your post is kind of confusing.... Anyways your temps are fine, as long as you don't hit 60c (load) you have nothing to worry about.....

I'm sorry for my confusing post :( 

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

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 :) 
September 8, 2009 10:41:56 PM

Thoes temp look really good... i see no problems... it all looks normal.
September 8, 2009 10:56:03 PM

you really should do more than 5min load, go for something like, 8hrs to figure out max temp
September 8, 2009 11:16:21 PM

My max was 1 hour long for Prime95 and still stays at 52c.
I'm going to do an overnight one when I'm done working on PC :D 
September 8, 2009 11:20:20 PM

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 !

One thing you have to remember is that when you test for 10 min you really ain't doing much to the CPU.... Try testing for at least 8 hours and then you will get accurate temps....

What is your CPU and NB voltage?
September 8, 2009 11:25:45 PM

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.).
a b K Overclocking
September 8, 2009 11:41:37 PM

Yea, 1.45v is way to high for 3.7Ghz....

1.392 is normally what the mobo will pull at 3.7Ghz, so in all go by what speedfan is telling you.....

As far as pushing the volts.... Just go by what your temps say and you will find out how far you can go... On my board i can go up to 1.53v before it hits 60c (AIR)....
September 8, 2009 11:56:56 PM

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 ? :) 
a b K Overclocking
September 9, 2009 12:03:09 AM

You can try running your CPU @ 4Ghz but don't expect a huge gain in performance... I would rather you run it at 3.7Ghz and make sure your temps stay low..... The temps will tell you if it is worth it or not... If your temps at 3.7Ghz do not exceed 48c then yes go ahead and try 4Ghz, if not then leave your CPU at 3.7Ghz and focus more on the GPU....

Another tip is to have the best cable management possible in your case, you want to make sure all that heat is exit'ing the rear and of course this will help overall temps....
September 9, 2009 12:32:19 AM

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 :D 


Thanks for your help guys!
September 9, 2009 7:08:50 AM

Alright guys 11hours of torture in Prime95
At 3712mhz it actually stabilised at 50c at the core !

Think we're safe :D

Do you have a link to your new thread?
September 9, 2009 3:29:45 PM

Here

However I'm kind of wondering if I *REALLY* need a RAID0 setup with 4 disks (or even 2)...

I am still considering SSD however cost to size really puts me off plus some horror stories when using an OS on them :) 


Let me know what you think !
a b K Overclocking
September 9, 2009 4:34:49 PM

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...
September 9, 2009 5:44:20 PM

Hmm wondering if a RAID0 with 4 of my Samsung Spinpoint F1s would be worth it then ;) 

Good thing with RAID0 you get full capacity...And disk failure...I don't care, first of all it's a Samsung which is reliable, second of all I'm backing up on external source/online so...

Wonder if my ASUS M4N72-E can handle 4 disks in RAID0 efficiently tho (Nvidia 750a SLI chipset)

September 9, 2009 7:06:25 PM

You really need 4TB's of storage?
September 9, 2009 7:11:27 PM

Don't NEED but if 4 disk RAID 0 is blazing fast, I'm sure I can fill them up. I archive all of my games on my PC and keep a database of my DVDs also :) 

It's also a HTPC since it's hooked on a 27" 1080p LCD so it helps !

September 9, 2009 7:23:42 PM

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...
September 9, 2009 7:40:40 PM

I'm at 1TB and got...120gigs free :D

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?

How do you reach 3.7 ?

I used 206x18.5 and 1.392 for VCORE

Also using 1.9v for RAM voltage (my default is 1.8v).

Other than that cooling wise I used a CoolerMaster V8 with MX2 Thermal Compound and I use a Scythe Kama Flex (massive CFM 120mm) fan as exhaust for my temperatures ! If PSU matters, I got an OCZ Fatal1ty 700w SLI approved.

Good luck!

Note that with my previous Asus motherboard (M3N-HD/HDMI) I couldn't go this far and ended up frying it and the CPU.
September 9, 2009 11:05:12 PM

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!!
September 9, 2009 11:22:20 PM

Sorry my mistake I am also at 18x206 :) 
Just had to raise voltage to 1.392v (according to CPU-Z, my Asus TurboV says 1.45v for some reason)


If case clearance isn't an issue I highly recommend a CoolerMaster V8!

Settled down to 50c after 12hours of Prime95 torture tests @ 3712Mhz, 1.392v (Small FFTs)

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)

ok, im running it at 3.8 now with those settings, but the NBv I've only got at 1.32, im gona try and push it up abit, my ram is also now at 840 so that pretty good. Cheers for the help.

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.

September 10, 2009 2:57:33 PM

You have to manually change the NB voltage to what I specified if you want a stable system... Of course Im just giving you an example of how to do it, the values might differ a bit but you get the idea....
September 10, 2009 3:16:29 PM

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.

Give it some volts.....

Run this:

Multiplier @ x19.5
CPU voltage @ 1.45
NB voltage @ 1.43
Leave bus @ 200 or raise if stable
September 17, 2009 9:07:09 PM

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?

Remember little by little, in increments....

Before you go any higher try running prime95 just make sure it is stable....
September 18, 2009 7:01:23 PM

just remember that sometimes that extra 200mhz ain't worth the risk / burned CPU :p 
a b K Overclocking
September 18, 2009 7:05:49 PM

Burned CPU?

In order for that to happen he has to either overvolt or overheat the CPU.....
September 18, 2009 8:50:53 PM

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.
a b K Overclocking
September 18, 2009 9:11:48 PM

Yea you are fine, just make sure you keep an eye on your temps every now n then....

Try lowering your voltage to 1.42/1.43 and see if you get better temps....
September 18, 2009 9:19:08 PM

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???
