Q9550 overclock.

setter · 13 Jun 2009 at 11:31

Had a crack at upping my q9550 from 3.4ghz on stock voltage of 1.200. Running 8.5x425, (3613mhz) upped the voltage 2 notches from stock, llc enabled, chipset voltages at.

PLL, 1.54
NB, 1.14
VTT, 1.14

Ram running at 510mhz ddr2, on 5:6 ratio, 5-5-5-15

P95 8hr run small fft

EDIT: Updated with 8hr p95 small fft run screen.

Opinions and advice appreciated that could help me push it a bit more.

Could maybe do with a bios update, thats what i had to do on my board to enable the 8.5 multi, im gonna be pushing the clock a bit higher once i get it stable at current settings, im almost 4hrs into a p95 small fft test, so hoping it holds out for a few more hours. Then im gonna try 3.8ghz then hopefully 4ghz.

Im gonna let p95 run for 8 hours or so as its nearly done, forgot all about ibt tbh, quite pleased with the temps so far, though i could lower them a fair bit if i swapped my pwm silent eagles for 2 of the full blown 2000 rpm models i have in the case. Will update as i go along, and thanks for the advice.

EO stepping.

Crikey, i didnt think there'd be that much difference between the 2 revisions, ive edited the op with a successful 8hr small fft test screen.

Yep ill be pushing mine a bit further, temps are a bit high for my liking. I may switch my two 2000 rpm silent eagle fans onto the TRUE to drop the temps, currently running silent eagle se, 400-1200 pwm fans on my TRUE black which are very dissapointing, i reckon i could drop 5-6c of each core, even considering lapping the cpu, as it made a vast difference on my old q6600 with my current lapped TRUE black.
