Asus M4a79 deluxe up close and personal

[eRazorzEDGE]

just 4gigs total? yes. i'm running the platinum 1066 2x2gb kit and they run very well.

[wez]

ok guys need some input here can our M4A79 deluxe actually support OCZ ram p/n: OCZ2RPR10664GK DDR2 1066 4096MB(Kit of 2)...tq

Running 2x2Gb reapers on my board atm, so yes they work. Tried most of the bioses out there as well with them. Only problem was I had to remove the HS from one of the sticks for it to fit under my TRUE cu. Although I'm not very impressed by their overclockability, it doesn’t take much to have them fail. But hopefully I just got a crappy pair.


Edit: Any vmod's around btw? Still looking for something to counter the vdrops

[chew*]

Yah the asus is really partial to the IC's that were used in the OCZ reaper/ plat lines and I was fortunate enough to get some failed ones in a gold kit that do very well.

i need help guys, i have the m4a79 and a PII 940, right now my best clock is 3500/2600nb/2000ht, vcore 1.475 bios /1.503 everest .

i have tried with and without acc, i have tried slowing my ram, what am i missing,

rest of the system is 8gb corsair dominator, corsair 850w psu.
watercooled at this voltage and speed my prime temp after about 3 hours is 110f.
im also wondering how the acc options work there +/- xxx %? whats all that about?

thanks guys

have your tried upping the voltages of other parts like chipset NB chipest and SB ? sometimes giving a little bump to those will help.

lastly has anyone touch that Nb 1.8 volt that's on the newer AM2+/AM3 boards ?

older AM2+ board don't have it

[9X23RNFA]

here is a list of my bios voltages
cpu vcore : 1.475
cpu/nb 1.2675
cpu vdda: 2.7
dram 2.14
nb 1.14
ht 1.24
sb 1.2

also i have tried changing that nb 1.8 it caused me not to be able to boot .

bump NB to 1.25

[9X23RNFA]

by raising NB to 1.2v, and upping my cpu/nb volts to 1.2875v i was able to get occt to run did a little 15min test at 3.53ghz , as for bios tweaking besides C&Q and secure virtual machine, is there anything else i need to turn off?

im trying to get 3.7 daily if possible with my current cooling.

[fuzore]

have anyone tries the new bios 1303 ?

Thanks for the heads up, I'll give it a shot tomorrow after class.

i am having one heck of a hard time trying to get my chip stable at even 3.5GHz. I even have it watercooled, and temps do not get high at all, havent seen them get over 46C at full load, but just had the Vcore at 1.47, and in vista x64, everest shows the vcore was 1.48, but when I started prime95, the vcore dropped down to 1.45, and prime95 was going good for about 20 minutes, and then my computer just restarted. Now I have upped the vcore to 1.48 in the bios, and am running prime95 with everest in the background to monitor and the vcore dropped down to 1.46, and my load temps are 44C on all 4 cores. Anyone have any advice?

I have 8 gigs of 1066MHz memory running at 5-5-5-15 2.22V. Everything else is stock, at first I thought it might be the 8 gigs running at 1066, so I took out 2 sticks, and dropped it down to 800MHz, and still nothing, I still have to up the Vcore way more then I would like to even get it stable at 3.4GHz.

[9X23RNFA]

try raising the Cpu VDDA voltage to 2.7v it helped my voltage droop.

can you list all your voltages ?

[FoxRacR17]

Ok I upped the vdda voltage to 2.7, and now with the vcore set to 1.4875 in the bios, everest reports that the vcore in windows is at 1.50, and when I put it under load with prime95 using all cores the vcore drops down to 1.46.

Vcore=1.4875
CPU/NB=1.3625
CPU VDDA=was at auto, now at 2.7
Dram=2.24
HT=1.22
NB=1.12
SB=1.35

[9X23RNFA]

as posted above raise your NB to 1.2v and if u have clocked your NB any i would run the cpu/nb to 1.2875v my NB is at 2639mhz at that voltage..


i use the turbo v to test settings in windows then run prime. after i find a setting that helps ill set it in the bios to confirm that it boots with the setting, did you turn off the c&Q in the bios? also did you turn off the secure virtual machine? might help.

Maybe your CPU just sucks. I need 1.55V to get OCCT stable at 3.6. Then again I swear I had it at 3.8 with 1.55V when I first got it... picture and all. No idea what happened.

I tried reading Vcore with my DMM and messing with the VDDA... did nothing for me.

[9X23RNFA]

any luck testing the new bios? (1303)

I had some weird overvolting on the shipped bios (1.51v'ish while set to auto), so that could be the reason I guess.
VDDA does nothing for me as well from what I've seen, although it might have brought me some stability at 2.8v, but very very minor in that case, nothing my DMM’s can pick up. Which is also the reason I run it at 2,8v 24/7.

Flashed with 1303 last night, but didn’t have a lot of time to test it out yet. Other than a quick sweep with the DMM to check the voltages, and nothing have changed there. Will play around with it some more tonight hopefully.


Btw, anyone experienced random USB drop-outs on this board? It started a few days ago for me, and nothing has helped so far. That includes running stock. But when I think about it, I got a new 5.1 system recently, and running it from the onboard circuit. Could it possibly have anything to do with USB ports dropping out? I’d assume 5.1 puts more stress on the circuit than a regular 2 speaker setup. Extra heat messing up the SB? Anyone seen similar behavior in the past?

in everest ultimate my benches for memory read and write were around 8500 using a 36gig raptor...ive now used a raid 0 setup using 2 80 gig wd sata drives and hd tach reads faster but when i bench using everest my write speed drops to like 6000....
im using the asus m4a79 dlx with 7750 dual core o/clocked to 3.1 ...im using 4/1 gig sticks ocz ddr2 1066....im confused as to why write speed has dropped..all other benches seem to be at or faster than before using the single raptor...any ideas or is this normal....ive not run a raid zero setup before......

Did you try any benching with the 80gb drives before raiding them? My guess would be that the 80gb drives are just slower than the raptor, even when raided. But its just a guess

@chew*
In full load, when the CPU is OC-ed, do those YAGEO coils make any sort of noise?
Just wondering.

[Jethro]

Solid bios finally. 1303 offers nice new limits for 100% load all day crunching.

Just for the record my NB is totally stable with 1.16v? Even at 230+ FSB. Testing 1.14v now as i explore the minimum. Dunno where the 1.25+v came from but it does nothing for my system even heavily overclocked. Maybe its for much higher FSB's then im running?

Raid 0 working perfectly here w/o any drop in benches. 100min / 125max mbs There is a HDperformance patch at AMD one can use if so inclined.

Honestly never paid attention......

replacement comes this week sometime.......

I will still help you guys out as needed with it however the majority of my work will be on am3 as they appear to need more work.

there is another new bios on there now also, 1402. Going to flash it and see how it is.

is this a beta bios... coz cant see it in the asus official bios page..

[soundood]

im running 1303 at the moment, and have noticed subtle changes in it, 24/7 clocks are now 3.7 gig @ same voltage (1.45v)

and i also can run the NB @ 2600 now without BSOD when custom c'n'q kicks in.

i wonder what the 1402 is going to give us? i will try and flash it later, after i run the scooter to Brighton (UK)

on s side note, i got stopped by the cops the other day, just so he could have a look at the scooter lol (he used to have one)
