yea the highest I trusted taking mine was 1.63v , Temps weren't a huge issue but I just didn't want to fry anything.

Prodigy, since the temps my question is about the card shutting down at any decent overclock? I,ve had it set to the "alpha dog" settings (740/1000) on my old mobo and it ran fine at hotter temps so I'm confused. Thanks for any help.

I'm trying to find a guide that is geared towards my bios on this Gigabyte mobo because I don't have certain HTT features so I'm having to translate from some of the AMD64 O.C. Guides I have. I am still trying to understand how fast my HT Clock needs to be and how to get this chip over 3.4 stable. I got a good feeling about this board but it has been finicky so far. Thanks guys!

Motherboard is ASUS m4n82 Deluxe (Nforce980a)
CPU voltage is 1.55v
Cooling is Xigmatek HDT-sd964 with two fans

I think my powersupply may be holding me back. Has anyone expiremented with the VDDA and VDDNB voltages?

(damn i gotta find time to update the top 30 gpu thread lol, update that thing takes like an hour everytime)
Great forum...the one that i looking for... :>
wanna enlisting...


Well, latest result...



History :
run at (200x16=3.2, 1.35v, 1800mhz(x9), at mem 800, 1.9v, 4-4-4-12, 2t) =
Crash when load os welcome screen.

i able to run at (200x15=3.0, 1.35v, 1800mhz(x9), at mem 800, 1.95v, 4-4-4-12, 2t) = run at occt about 2 hours b4 bsod (6h test)
In real life app i'm running more than 1gb video encoding, simultaneous run nfsp more than 2 hours, after i quit the game, os constanly crash.

Now i am currently run at (200x14.5=2.9, 1.35v, 2000mhz(x10), at mem 1066, 2.1v, 5-5-5-15, 2t) = run at occt about 8 hours b4 bsod (10h test)
In real life app ulead encoding more than 1gb video, in same time burning 8gb dvd data with nero, and quake 4 online. No Crash, but temp going nuts its 55deg.

i wonder if people would answer my curious, is 2900 is limit for my 7750 chip ?
or i'll appreciate if d' masters here could give any advice how should i breakthough to 3200, stabilize occt test in 10h, and normal in real app life.

most use of my 7750 is for encoding pupose, just common gamers kindlike...

i suspicious the crash matter is to do with temp, yes..i have problem with temp, in here (jakarta) air temp is 'bout 28 ~ 35deg, my pc run 46 at idle, and 57 at full load (7750 official max temp is 'bout 74deg, ...cmiiw), so about thi issue i enabling cool n quiet feat in bios, hoping this could help, but its almost none...

ps. : i'm also enabling hybrid crossfire (if this would concern the temp issue)

First time poster.

Hello , this is my first attempt at overclocking.Im currently being conservative at 3.0ghz havent tried to up the multi past 15 yet , so far so good.System hasnt crashed once.I will attempt to see how far i can push this chip later in the week but with my aging graphics card the overclock prolly wont make differnce anyway.

Very pleased with what 65 bucks can buy in cpu's in todays market.

MHZ - 3000
Bus x Multi - 200 x 15
Ram speed - 1066
Voltage - 1.33
HT Link - 1800
Mobo - Gigabyte GA-MA790X UD4HP
Chipset - AMD790X
CPU Cooling - Stock

Well, don't know how or why but I'm getting some good overclocks from my gfx card now! Here's my settings and so fsr so good but a couple questions. My CPU Core stayst the same at idle/load but the CPU temp rises about 4 degrees? Ram Timings vs speed good (it's ddr2-800 but has ran at 996 under non-mobo/cpu stress conditions) Also if I push the CPU multi or FSB up any I get crashes so thats what I would like to do w/out frying my chip/chipset (2oz copper base on mobo)


Suggestions PLEASE

Ok so I am no professional overclocker to say the least (I am stuck at 2.9 myself) but I do have some input on your post

1) It has been found that certain batches of these processors OC better then others, from what I have read there are some that sit at 2.9ghz on stock voltage and need a massive voltage bump to get over that mark and then it seems for the lucky one's they get to about 3.1-3.2ghz before needing that voltage bump

2) Cool and quiet is going to make you crash more, with cool and quiet to be effective the multi and all other settings need to be set to auto so when the processor loses voltage from the down clocking cool and quiet provides the multi drops as well, if not then your chip continues to run at that higher multiplier with drastically reduced voltage, just runs out of steam and crashes. I have read that the new phenom II can OC and run cool and quiet and I am not sure if that has to do with the chip or the chipset so i could be off the mark here but this is definitely true on my board and processor combo.

If I am mistaken on any of these points please let me know. I hope this helps, I was able to get mine a little more stable when bumped to 1.5v but still would crash within 15-20min of P95 small test. Wish you the best of luck in getting past this, so far I have been eluded..
