Hi guys

I manage to OC my procs yesterday.
Here is my picture..


Q6600 2.4GHz OC to 2.88GHz @ 320MHz bus speed
Pros:Memory = 1:1
Kingston value ram DDR2 667MHz -> 640MHz
5-5-5-15
Ram multiplier X2

My HSF is ori/stock..

My 3Dmark06 reading went up from 12348 to 13786
My temp fluctuate from 53 to 59deg C puring Prime95 (small FFT) test.
Pass..

Question:
1)Is my reading for the 3Dmark reasonable?
2)Is the Procs temperature reasonable?
3)Can i OC further to 333MHz bus speed with my stock cooler?

thanks, your comment is valuable...

(thanks to Kmarc guide to OC, i manage to get it step by step )

thanks....

I did adjust the vcore abit... not that much only....

Yup i ordered the sigmatek red scorpion S1283. Planning to OC till 3.6G at lease. New ram comming too...

thanks for your comment

hi guys..

Just received my xigmatek today for my OC PC.
My spec:
Q6600
OCZ Platinum Rev 2 PC6400 DDR800 2G (dual channel) (memory set to 1:2 ratio)
Foxconn Mars Board
8800GT Zotac amp 512MB
CM450W true power

1) Please refer to my setting the picture below

- I set the cpu voltage to 1.35v
- I tested using Prime95 with small FFT (it was ok for 20m) tested pass
- When i tested with 3Dmark06, the result is as in the picture. Stable

Then i increase to 380MHz, the PC boot. and when i tested with Prime95 with small FFT, it passed as well.
however i tested with 3DMark06, in the middle of the test, it hang and reboot. But the buss didnt jump to previous setting.
buss speed still the same 380MHz.
Is this normal? what should i do next?

2) Then i decided to lower the cpu multiplier to 8 as shown in the picture below.

- Memory bus can reach 400MHz with the same voltage
- I tested with Prime95 with small FFT. Passed
- Tested with 3Dmark06 too.

Then i increase to 410MHz, same thing, passed Prime95 but failed 3Dmark06 (reboot)

I know my processor can push further but i dont know what to do already.
All temperature is witin the safe range (below 65deg C)

I dont think it is my ram issue because the Ram can be OC.
need advise what to do next.

thanks.

Yes, i have set the Vcore to 1.35v in bios.

According to your guid, the reading in CPUz for vcore should be lower than the actual voltage in bios vcore reading.
From my pic, my Vcore in Bios is 1.35v
My cpuz reading in idle is 1.352v
vdrop = -0.002?

during load my cpuz vcore is 1.336 - 1.328 (changes)
then my Vdrop should be changing from 0.014 to 0.022v

should i push my vcore furthre abit?

ha ha... i can see you are having the same GHz as mine. but your Vcore is higher than mine... I will try again..
I am suspecting the PSU. i saw the review for this motherboard, the bus speed can reach 500+MHz... sigh... look at mine is like.... shit.....

by the way, i am using a CM450M real power. The efficiency is 75%. i saw the product range, after this series are the SLI already. So i was thinking this should be sufficient right since i am not in SLI mode.

I think the 8800GT 512amp is not power hunger compare to the old 8800GTS and the GTX series... so i think this should be pretty safe. correct me if i am wrong..
yeah, my psu is CM450Matt true power. no much hard ware, only 1 DVD writer, 1 HDD, 1 GFX, 2 casis fan and one blow out fan for the GFX.

If mine can hit 450MHz X 9 is the best lo but if 450MHz X 8 also ok... 3.6G already...

yeah... actually i think i should feel satisfy to OC till 3.2G... I prime95 yesterday over night... running stable..
I see whether can do 3.4 or not with 1.4vcore...

3Dmark06 hit 14k+....a bit greedy because i was trying to hit 15k benchmark..

my card is already OC by factory default... ke ke ke

hey dude... you push higher also la... i will post more result tomorrow... you post yours also ok... ke ke ke...
i saw the tomshardware review... It is pretty normal to reach 3.3GHz cpu without changing the multiplier

just sharing...

my Q6600 running at 1.42 Vcore, 400X9 = 3.6G
Temp idle = 43C, Load Max = 60C

heatsink fan: Xigmatek Scorpion
Therml past (very important!!!!!! MX2 or Tuniq)

i used to use capalang thermal past.. temp was 65 at 1.37 at 3.2G.. but now can go somemore... woohoooo

credit goes to cstkl1.. he thought me how to OC my processor with the Biostar I45..

trying to hit the 4G Bench... actually with my current voltage setting. i can esily hit 3.8G.. let me do more test first.... will share here...

personally i think if can hit 4G with Air colling is consider ver very good performance... notice not many people can get that...

the board helps alot... with foxconn mars... i cant hit 3.6G stable....
this board is great....

HWMonitor from CPUID and OCCT.. open either one software only to monitor....

i tihnk the tpower2 sotfware is more accurate... it is very similar when i use the OCCT to stress...

try OCCT... more intense stress.... if you pass OCCT, the rest should not be a problem.
