Decided to push my 920 a bit more

setter · 7 Apr 2011 at 20:41

Thought id have a crack at upping my i7 920 to 4.2ghz today. Decided to try the voltage settings i use on my current 4ghz profile.

1.29375 vcore
1.32500 qpi
1.66 dram
ram at 1603mhz, 9-9-9-24 2T

Changed multi to 21x, selected 5 passes of LinX as a quick stability test, bsod on the second test. Highest core temp was 78c at one point, lowest at 71c. Gonna try with another jump on qpi voltage.

nice one setter your rocking now bud.

setter · 7 Apr 2011 at 20:53

Tried again with +1 on qpi, this time LinX stopped on an error after 2.59 secs, (least no bsod this time).

I'll send you alittle help m8.

OLDPHART · 7 Apr 2011 at 21:08

Just sent u the little help.

setter · 7 Apr 2011 at 21:20

Cheers mate, will have a look at it now. currently running linx, posting on my other pc. Its more of a museum piece.

setter · 7 Apr 2011 at 21:29

Well, things are looking a bit better now.

Only a quick 5 run pass, but progress is progress lol. Upped vcore to 1.300, qpi at 1.33125. Temps are pretty impressive as im in a room with the heating on, (23c), also my prolimatech megahelims and viper fans could do with a clean.

OLDPHART · 8 Apr 2011 at 08:59

LoL, your still using the cen-heating its been quite nice at night, but saying that you'll get to check your temps and if your CPU temps are ok now, no need to down clock in the summer.

Nice 1 bud.

you jammy gits!

for 4.2GHz i need at least 1.35Vcore

jbloggs · 8 Apr 2011 at 10:17

Good chip you have there setter, same cpu voltage as myself to get 4.2GHz (1.288v in windows, 1.300v in BIOS), qpi 1.25v, will you go for anything higher?

setter · 8 Apr 2011 at 19:48

Never downclocked this chip at all tbh guys, it's ran at 4ghz, (albeit on various multi/bclk settings) since i got it, september 2009. Temps arent too bad, id love to put it under watercooling, but with 2 x 470 gtx gpu's, the cost is very prohibitive.

jinxpad · 8 Apr 2011 at 20:29

could always just cool the CPU then add the GPU blocks as you go

OLDPHART · 8 Apr 2011 at 22:18

Come on setter m8 you can crack it, l,ve got a feeling you'll do 4.3 in the end.

Got my 920 4.4GHz > Bios-1.3375v CPU-Z-1.328V 100% load, so far l,v tested it with wprime 32m which is not a bad quick stabity test, IBT 10 passes, heaven and custom pc bmrk, will finish testing it for stability tomorrow.

Thats what l told him that as well jinxpad via re-ply email, best way to do it.

I could probably go higher, but it would involve high powered fans, like deltas, and theres only a few fan controllers that can handle those beasts. Lamptrons iirc, definitely not fans you attach to a mobo header.

callumburns · 9 Apr 2011 at 03:29

4.4-4.5Ghz would be do able on 1.35v-1.375v with the right kind of cooling

good chip you have there mate.

setter · 9 Apr 2011 at 03:35

Yeah, it would be nice to push it higher, but id say im knocking on the door of the limitations of air cooling. But, tbh the system is major overkill for most of my needs, primarily a gamer and i never experience any bottleknecks with my gpu's, able to use loads of aa/af in game without any issues.

bifday2k · 9 Apr 2011 at 03:36

Yeh just need to get that base clock up abit. which your mobo should be able to handle comfortably.

And yeh the lamptrons are the controllers best to use with delta's.

OLDPHART · 9 Apr 2011 at 03:42

Cheers callumurns, your not doing to bad yourself AMDII 1055T 4.0GHz, nice one. I'm waiting to see what bulldozer will do, even though l have a intel most of my early PC'S were AMD. My barton is still going strong to this day l give it to a friend[a silver surfer].

No worries

and thanks mate, thats with a Hyper 212+ cooling it. Tried more but at 1.475v its getting pretty high especially for air cooling. I'm so surprised that such a budget cooler can keep this chip cool even with a heavy overclock! but then again it is the 95W chip.

I'm so tempted just to go Intel to be totally honest with you so i can go Nvidia with a bit of SLI perhaps but Bulldozer is so close away

My first ever pc was an amd, a64 4000, s939. I still have it, asus a8n 32 sli deluxe, 2 gb corsair 3500 ram. Still working, got an 8800gt in it. Its housed in one of my akasa eclipse 62 cases, tbh i dont think ill ever get rid of that machine. I was so proud after finishing building it and it worked first time. Kinda man made fire moment tbh.
