Btw, whats the thing with the memory overclock? I get better results from many benches with memory only 800MHz versus 1140MHz.. and when clocking from 1066 above the points starts to lower in different benches.. weird?

All depends on How how the NB is . the Timing at 800 MHZ plays a role too.. 1066divider usually likes 5-5-5- or higher especially above 1100mhz. Some apps like it some dont. Ganged and Ganged is also a factor as some programs run better in ganged and some run better in unganged.

I usually set the sytem up to perform at what I play the most . If i game Tighter timing High NB allows more response along with High HT.

Movies and or heavy apps 1066mhz and unganged can optimize the ram for bigger loads with stock HT and High to meduium NB..

Just see what programs or games you like most and set your rig . If you game,, Low latency is key with High Bandwidth.. You just need to find the happy medium .

Phenom has lots of ways to tweak and by all means theres no easy way . Unless maybe one keeps the system stock . Then you would just boot and play what ever and never know its true performance

Im a performance person ( Stock) is a unknown wierd language to me.

you drunk? ..

But to the subject, the timings were the same 5-5-5-5-15-2T unganged for both frequencies, and NB speed was too the same(2400MHz).. thats why I think its a little odd. Oh well, im getting day by day more into this system, I like it very much.

Its just little sad that I still cant get this 247 stable above 3.1GHz, still the rebooting issue.. it just comes under heavy cpu-load no matter what I try. :/ And the older bios wont boot at all if I try to clock.. even 15x200 fails to boot. Just black screen.. and have to clear the cmos by jumper to get it back on.

Well well, now to sleep and then some more testing until my phenom 2 arrives

Now I have got the settings about right for 3.1GHz and maxed the performance for that(all I can do for now). 3dmark06 cpu gives 4600-4610 now. Cinebench gives about 9950 and wprime 32M 12.4sec, superpi 1m 24.5sec. And this is for 24/7 stable.

Hmmm the NB could have been under stress @ 2400 when running 1140mhz..Thus can slow down the CPU L3 /Slower results if the NB is close to max . While @ 800mhz it can handle the lower freqency just fine with out slowing down the NB.

Also the Ram Divider being used can affect the NB L3 speed @ 800 vs 1140 even if the NB speed is the same.

@3.5ghz,,My ram @ 1173 is faster on the 1/2 Ram divider vs the 3/8ths Ram divider even at the same NBspeeds Same CPU Speed . The thing that changed was the CPUxmulti and Ram multi @ 1173.

@ 3.5ghz 293x 12 gives me a 1/2 ram multi.
@ 3.5ghz 220x 15.5 gives me a 3/8ths ram mutli but slower latency.

The cpu multi affects what multi the ram runs on. This could explain what your seeing happen when running 1140 vs 800 in the same Ganged or Unganged mode.

Na ,,
not Thunk yet ,,
to early to Drink.

Update,, Using Vista32bit ,, it can run 5200HT total I tried with XP and didnt think i could get the same results. I havnt tried for High Clocks with HIGH HT since. I just wanted to see how much HT would go with High NB on this OS. Not too shabby .

3380mhz with 2600NB and 2600HT Ram1040mhz



3500mhz with 2600NB and 2600HT Ram1040mhz



3523mhz with 2610NB and 2610HT RAM 1044mhz
Highest stable Clocks with Vista32bit.
This is my max best for everything HIGH



OMG i tried this just for KICKS 3537mhz 2620NB 2620HT

This set up scares me lol. Ok no more i quit! This made me Beer foam,, Ive never ran 2600+NB and HT over 3.5ghz Never, Need More beer and that was with XP. Vista 32bit just shocked me real good !





Theres not to much more i can get with this 9950 and im waiting for 45nm before i bite on another chip.. This has been the Most Pleasing system for me out of all Phenom to date ive tested. It can truly Clock in more ways than one.. Phenom offers a lot to play with.

This ASUS 79-T is a real Joy to make boogy if ya know what i mean. I cant wait to see what newer Asus bioses will bring with B3 and the New 45's to boot

I couldnt rember if i had posted HIGH HT with this Mobo ,,sorry if its a repost.

LOL, man those are some sick nb/ht clocks. I cant say i've had mine over 2.2, mostly because i never felt the need. You think it has any effect on benchies? I wouldnt think it would too much, for the simple reason cpu-mem is on a dedicated bus outside of the htt/nb, so i usually drop my multis on them so they're dont interfere with anything. So far i've got this 9850 benching at 3450ish, highest cpuz valid was 3534, but given the fact that i ran at 3534, got the validation, and didnt crash right away, is telling me this chip has got some more balls, next stop, 3.6

BTW, i figured out how to hit 1.9vcore, believe it or not, 1.7vcore from the bios is 1.5vid with +.2v boost from asus, AMD OD let me ramp the vid upto 1.55 with the +.2v boost. vcore from cpuz was showing ~1.83, with 2.8v VDD, running wPrime brought it up to just shy of 1.9, like 1.893 i think. Of course, everything shut down from a thermal overload, thought i bricked the chip for a minute, then it booted up lol. Checked my logs and the temps went from 33c to 84c in about 5 seconds, fried eggs anyone?

gOtVoltage:
PUT DOWN THE BEER AND STEP AWAY FROM THE BIOS

Dude, I agree the Asus 79-T is probably the best AM2+ board out right now...
If nothing else, you make me confident it can handle some punishment.

[gOtVoltage]

Funny,,
Im trying for 18000 in 3Dmark06 with my Single old 3870x2 i grabbed back from my Neighbor..

So far 17900 When i hit 18000 ill stop

This thing Rocks @ 3537 and 2620NB 2620HT,, Its cranking

Few more Beers ,,few hours later

I never though id see this,, Now im Done,,






The 3870x2 on Stock Air ASUS 79-T rocks..this card would not go above 918/1099mhz on any other mobo i tried @ 3.5ghz.. its way above that with no Voltmods.

Unbelievable, this Mobo let My Vidcard oc like Crazy even with cpu@3550mhz with high NB //HT. This hardware has never ran this High on any other Mobo to Date,, Including GX3/SB750 and 78-T. This is Night and day overclocks from all mobos ive used with 9950 and 3870x2.

ALL AMD Baby,, beer talking ,,Good Night now that i Broke 18000

http://service.futuremark.com/compare?3dm06=9249738

Only mod ,,i used MX2 on both GPU's with stock ram pads.



I just Bench alittle ,, then Raised 1mhz at a time.. i truly didnt think it would work this good. I think I found the sweet spot.

Same BIOS SETTINGS USED for all OC,,except only Raisng HTT and CPUxmulti from 3380mhz-3550mhz







Kept Ram on Auto timing and Ganged but only used the Highest freqency My Ram would allow for all speeds achieved.

This is my 24/7 volts that i used with My Old TA770,,only differance is ACC+4 to achieve a 100+mhz Oc over the Ta770.Im Happy and Yes ACC really works. I just had to give it a chance after many mess ups with the 403 and 502 bios. The 602 is sweet.

[oc_junkY]

hey all,
i wanted to give amd a chance and sold the asus p5k pro, e6300 and some 3gb ram to a friend. i bought a m3a79-t, amd x2 5050e, 2x2gb ram which do around 475-500mhz cl5 with 2.1v.
now i'm messing around with this setup as my first amd system for overclocking since, ehm, ever ;-)
i'm really not familiar with it and can't find any overclocking results with this 5050e.
how much voltage can these cpu's take? is there any degrading noticed so far with amd chips? i read that this is a x2 with a phenom core, is this true? and if so can i compare the clocks/volts between the 5050e and phenoms?
what i really want to say is: is there anything i _must_ know to get good results from this board and/or the cpu?

thank you very much at least for reading this
junkY

p.s.: i bought the cpu because i didn't want to spend too much money right now cause i'll the phenom 2.

hey, welcome to AMD..again.. The 5050e is a Brisbane and is not based on the agena(Phenom) core. I run 1.44v through my X2 4200+ (Brisbane). sits at 3.0ghz from 2.3 stock. never went higher tho.

ALL time best with 9950(140watt) this Mobo Rocks

"Hondaguy ",,
this is my Best! No More Left. Its maxed..this made me Open last Beer Lol

Exciting clock gOtVoltage

here's a little result so far:

This is a 1.4v set in bios, which is the maximum voltage i can set for cpu vcore btw. why is this?


When do i have to raise the NB/HT voltage and when the NB/Core voltage?
When i raise the bus speed and lower the multi, do i have to raise voltage at all or do i only have to raise those voltages when the "HT Link" speed gets faster?
Do i have any advantage of a high bus speed with a low ht multi? and does this ht link effect the cpu so that i have to raise the cpu vcore?
so many questions, i hope i'm not already going on your nerves

[crazydiamond]

320htt is good! id bump the multi back up a few and lower ram/ht link and push the htt from there to see if you can get higher core clock

[oc_junkY]

320htt is good! id bump the multi back up a few and lower ram/ht link and push the htt from there to see if you can get higher core clock

i'll try that. is the ht link hold back by cpu or nb?

[gOtVoltage]

i'll try that. is the ht link hold back by cpu or nb?

Your off to a good start,,

Ht can only go as High as NB By NB,,it can not go above NB's highest freqency. But the Nb can go above and beyond HT.

Concentrate on Clocking up the CPU with close to Stock HT/NB..Use a nice low Ram divider that keeps ram below or close to 800mhz. this way you know the ram wont hold you back.


I Only Raise the HT voltage if the Sytem starts becoming unstable. I usually keep it @1.28v is a safe range. Stock is 1.26v

The CORE /Nb I set to 1.32v (stock is 1.26v)this will help the CPU Clock hihger especially when the NB goes High.

You can run 1.32-1.34v fairly safe on CORE-NBchipset..this helps stabilizes the ram Slots on Mobo helping the NB on the CPU/IMC. Especially when running tigh or High freqency ram.

You can go above 1.4v with 79-T.

You will need to Disable Voltage monitoring in Power menu if you go above 1.6v. I usually set the VDD @2.8v and raise the CPUvolts first then when i Oc the NB i slowly raise the NBvoltage(cpu) as i raise the NB evey 200mhz..

Try to Clock with ACC off first. If i feel im at Max Clocks(unstable after a while) may need just a little volts ,,Ill then use ACC +2 or maybe +4.

Oops,,Note: NBvoltage and Freqency will only apply if you have Agena/Deneb..PhenomI PhenomII core type CPU's..You should not need to worry about setting those options. You will need to Raise the CORE/nbvolts ..thats the Chipset on the Mobo which controls the ram slots. it helps with all X2's and Phenoms. I would not have been able to Clock my 6000+ up to 3.5ghz F3 with out it on any mobo.

Make Shure your are using Manual Overclocking Mode NOT STANDARD MODE too.

Hope that helps,

[MattiasNYC]

So I've got my mobo/cpu/sheit up and running and I have a couple of questions. I've read through this thread (well, at least about 20 pages) and the manual etc and I'm not sure about the answer;

1) Is there a performance (or other) benefit to AHCI?
2) Can I simply enable AHCI although everything (WinXPx64) is installed already or will I "loose" my OS installation?
3) I find no info on the eSATA hot-swap. It only says it's possible. Is there any particular procedure for making it work?

Any help would be sexy!

thanks,

mattias

[LC_Nab]

Wow thanks for all the info guys this mobo sure is awsome and im sure it would be kick ass for the Deneb chip to come .

[crazydiamond]

he is on a dual core until pII gOtVoltage

oc junky, ht link afaik doesnt affect performance until it drops very low, and can help increase stability if kept around 1000, too high can cause instabilities. like gotvoltage said, keep the ram divider low and ht link low and see how high you can push your htt with your 13 multi. i think as long as your mem speeds stay in spec (they go up w/ htt) and your ht link stays around 1000 you should be able to find your max core clock (need to bump nbV, vdimm, vcore). then from there you can pick a multi/htt/mem combination to get you close to your max core clock and that will also oc your nb and ram

I too have the m3a79-t dlx board paired with a 9850BE. Im usuing crucial dominators with the stock 5-5-5-15-2t @2.2v and a visiontek 4850. Im having issues getting it to go above 3.2 (200 bus 16x mult @ 1.48v cpu/nb stock nb/ht speed ACC 4%) If i go above it, say to 17x mult my 3 and 4 cores fail at self test in prim 95.

Right now im running at 3420 with my mem timings at the above, the mem div at 1:2, mult at 15, bus at 228, acc still at 4% HT/NB @ 2280 with voltages at 1.6 for both CPU/NB running stable (to me stable is running WoW for over an hour :-D)but 3 and 4 core still failing.

I can never run half mults (i.e. 15.5) My cpu is h2o cooled.

Anyone have any pointers on how i can squeeze some more out of this thing? i'm seeing people get 3.5 - 3.6 What are you 9850 owners out there getting as far as settings??

1st ,,
use 1.65v for CPU and keep NB @ 1.55v this will even out the voltage in the CPU better..Your temps will be the same. The CPU needs more and NB less.

Second,,
CORE PCIE @ 1.32v.. This makes it easier on the IMC at high loads.Helped my Dominators alot.

@ Gnaged vs Unganged ..
Mine gave Me Oc problems above 3.45ghz running on the 533 divider. Vipers with same settings can run cpu to 3.6ghz. The dominators really held me back and i had the D9 version.

Mater of fact im running@ 4-4-4-5 24 2t unganged with Vipers where the Dominators would only do 5-6-6-5 20 2T..

I can Run Unganged with tigh ttiming and faster overall speed at high Overclocks,,Where as Ganged would crash my nb or cause unstibilities at the same exact Clocks/freqency..It one big crapshoot i tell ya.

If two cores are failing and going at the same time i would say they dont have enuff Vcor for 3.4ghz. If it was just one core id say the chip is maxed.

Your Chip may like higher htt with low CPux more. Your water cooled so hopefully temps arnt the issue.

[emersonsc]

will try that thank you

how would i get my vcore up?

and what is CPux?


also, w/recommended voltages, 3 and 4 both still fail right away in prime 95 :-/

[gOtVoltage]

how would i get my vcore up?

and what is CPux?

CPuX = CPU multiplyer for short.

Use VDD 2.8v

In the power options in Bios You want to disable CPU voltage monitoring

Menu should look like this..Scroll down to Vcorevoltage and disable it .. this way it wont stop the booup with a volt warning.



Then you can set the CPU voltage to 1.65v

And NBvoltage lower to 1.55v instead of 1.6v..I use 1.6vnbvolts only when running higher than 2400mhzNb

maybe try More or less ACC+/-

[emersonsc]

well i was doing some adjustments on the mutiplier... and im pretty sure my mobo just took a s***t on me... it restarted as normal after saving the changes, went to boot into windows, and just restarted, i got my asus splash screen, then... black screen. I tried to clear the cmos... nothing.

[crazydiamond]

try a battery pull?

[emersonsc]

should i wait any specific amount of time before putting it back in?
