Windows vs. Linux

post #1 of 5
Thread Starter 
im not sure if this one is just me of if anyone else has experienced this but ive noticed ive been able to get really high overclocks that are stable in Linux over my Windows 7. i hit 4.014ghz stable in windows at an uber high vcore but i can pull 4.2ghz stable in linux with a slightly lower vcore but not by much its still sitting above 1.5 in either os. whats strange to me is the fact that this happens maybe its because Linux is less system intensive than Windows wich allows for higher over clocks but they may or may not be as stable as windows and it just doesnt affect Linux the way it does Windows. if any one else notices this or can prove or discredit this please let me know because im very curious to find out if this in fact is true or not.

UE Linux 2.8 x64

Clock 4200mhz
vcore 1.56V
temp 41C - 52C

Windows 7

Clock 4014Mhz
Vcore 1.62V
temp 45C - 66C

Windows uses more resources that all there is to it.

To bad you cant really stress in linux like you can in windows.


I will say 1.62V and 66°C is asking for failure.

(Your rig is REALLY REALLY similar to mine.)

I got a 550 2 at 3.9 @ 1.4V
MSI 750-g55
Muskin 4 GB (1600)
Seagate X3 (Raid 0)
and a modified HAF 912 (I put a window in mine)

First off, yes you can stress in Linux just like in any other OpSys, with the only important exception really being DX 11 game timedemos. You can run Prime 95 Torture test for CPU/RAM as well as Memtest 86+ and for 3D there is SpecViewPerf and others.

As for clocking higher in Linux that is not a given since it depends on the kernel you are running, which is really all Linux is. Distributions package Desktop Environments and applications. For those unfamiliar with the term "kernel" all operating systems have one. It is the most immediate extension of the system's BIOS and handles the communications between software and hardware and most importantly to performance and overclocking, the timing.

These features of how hardware works together with software at this low a level (basically "right on the metal") are not adjustable in systems like Windows for licensing reasons. They are adjustable by several means in Linux. So what OC works with one kernel, may not work with a more aggressive kernel, but performance may actually be higher, especially in how it feels since latency can be so incredibly reduced.

i agree stuffstuff1 1.62V @ 66c is asking for failure thats why i only left it that high for a short bench mark and stress test to max out the temp you would have to be crazy to try to operate at these extremes longer than necessary to bench and test.

also how did you go about adding your window to your 912. i havent started mine yet im still in the planning stages of exactly how i want it to look.i would like to see yours if you have a few pics of it.

as for my ram i need to update it and a few other things im now running 8-8-8-22 timings at 1333mhz at 1.6v i want to try to shoot for 6-6-6-19 but im not sure how the xms3 will handle it.

Cool on the overclock. Have fun not doing a lot with linux.

You should be able to pull a lot less voltage out of that chip to get 4GHz. I'm sitting stable at 1.52V, not exceeding 40C (haven't checked real temps since I cranked the fan to 2000RPM instead of the traditional 1100).
