msi 790 fx-gd70 thread

Hey Massman - actually i really didn't pay attention. It was the last thing I did before going to bed :P

I will still be on phase tonight, while I work on something else. I will see what my max Spi32M is at that timing.

What is the highest you seen that is SPI32m stable on AM3?



Hey Chew - Cool. Great to hear. there maybe more in this CPU

I do have a question.. Will upping my NB speed and volts TOO much have the same effect of not keeping the IMC Happy? I did notice on the GB mobo when I up the vNB too much, SPI32m didn't run. Even at Low NB Speeds. (p.s. I hate bios that say +.01v, and don't tell you what the starting voltage is)

Well.. hopefully keeping everything spi32m happy, i will be able to hit 6Ghz bench.. if I can.. there will be some interesting results by Monday

I think you will find that as you increase NB you will have to back down your ram speed.......as its driving your ram harder........that could explain your higher than avg ram speeds.........

I have no issues cranking NB on an ancient mach 1.........I suggest your try bringing it up to 3000 and restest your ram speeds before you waste LN2.

Hey Chew.. I was did test NB on Phase last night.. I was doing 3Ghz NB just fine. I am sure I will have to turn down ram speed when I crank up NB, but I need to do it under LN2.

I need to see how fast my ram can be when NB is at 4Ghz+, which I can't do on Phase.

So we will see how that goes tonight.

If you were pulling 3000NB at that ram speed on phase and it ran 32m with the CPU clocks high you will not have to back off at all 3000-3200 is max stable your going to get on phase for NB.......needs more cold to scale even on DI thats almost the limit unless you sacrifice CPU speed....... say 4400 CPU and 3500 NB or you can run 5gig with 3000NB, 5000 CPU is obviously faster for DI

LN2 really wakes it up.

Have fun.

Massman.. do you mind PM'ing me and sharing your insight on that 960 Mem thing? It apparently appears to be real.

We'll, there's nothing more I'm allowed to tell you ... but frankly, there's nothing more to say than what you already said yourself: there's a limitation around 960MHz and it's definitly not the memory or any other overclocked components.

There's no easy solution to this problem.

Hey Guys..

Wanted to share my results with my memory testing with this board. Massman.. do you mind PM'ing me and sharing your insight on that 960 Mem thing? It apparently appears to be real.

I was not able to run Spi32m at 960. It was VERY flakey. Sometime I hit 960 and it locked.. some time it didn't. I am sure it would not be able to run 32m w/o some tweaking, which I didn't do. I was able to run Spi1m at that speed. At 964 it locked up no matter what.

People might say that the 960 is the limitation of my ram, which I can say is definitely not. If I can runs the speeds I listed at 952 / 956.. a 960+ run should have been possible. 960+ may be possible w/ more / heavy tweaking and more voltage.. but I was getting bored watching SPi32 m. :P

So ain't crap w/o screen shots.. so here goes Side note - All ram was at 2.2 ~ 2.3 volts. I thought adding voltage would help, but it really didn't. I think I ran higher volts on one, and lower on the other. I am sure it would have all been stable at the lower volts, but wanted to factor out volts as being the limiter.

Spi 32 Cas 9 @ 956Mhz (2.2v ~ 2.3v)


Spi 32 Cas 7 @ 952Mhz (2.2v ~ 2.3v)

Spi 1m Cas9 @ 960Mhz (2.2v ~ 2.3v)


Spi 1m Cas7 @ 960Mhz (2.2v ~ 2.3v)


I really have a feeling I might be able to do like 900+Mhz w/ Cas 6-7-7. Might have to give that a try.

Let me know if you guys have any questions.

- Ton

PS - its a pain to try to crank up NB Speed on phase :P Should be going to LN2 tonight, to see if I can any increase stability on my CPU/NB for 3d Benching.

crazy good clocks with stability. these are not stable as chew* has beaten into my head but 900+ is possible @cas 6 mine were again not stable with these clocks but i was able to get SS of them

[SNiiPE_DoGG]

wow CDA that is some really nice work there! what ram sticks are those?

[cdawall]

they are D9JNL based crucial value PC8500


and the sticks were under DICE and vdimm was 2.4v-2.44v

[SNiiPE_DoGG]

oh well that explains alot

Hey CDAWall,

Very nice cas 6 @ 900. I didn't try pushing it much over 2.2volts for tweaking at cas6. I found cas 6 @ 860 to be the sweet spot in regards to voltage. I will probably try to kick it up higher, but don't feel like scaraficing the rams this early in the game Need too many other things to tweak first. Once everything is all dialed in.. going crazy a/ the voltages

I must be doing something wrong as I can't get a bus clock stable, I've tried everything I can think of and finally gave up and just went for a high nb + ram clock with decent timings. Is there some setting that I am just missing here?

[Sparky]

3.6GHz stable with 1.38V BIOS (1.36 actual under load) for over 3 hours on prime. Tweaked the PLL voltage a tad. Bumped the multi up to 19 for 3.8GHz and it is a no go again, I've been fiddling with vcore and PLL volts and even NB a little and getting nowhere

Considering it took only a small bump to get 3.6GHz, I feel I must be doing something wrong.

[hellcamino]

I swapped out the 2x2gb kit of ocz 1600 and put in a 2x1gb kit of 1800 and it seems to like the 2x1 kit of Crucial much better, currently priming 3.8ghz (200x19) ,NB at 2.8ghz (200x14), and DDR3 at 1600mhz 7-6-6-18 1T (unganged). Any bus clocking I've tried has resulted in instability, I've even underclocked the cpu and run the nb and ht at stock with the ram at 1333mhz 8-8-8-24 and still fails as low as 205mhz so I'm thinking I must be missing something as well.

[TiTON]

Hey Guys,

Ok.. last night i was on LN2 w/ the MSI and the 955. I spent most of the night trying to dial in the ram and mem under cold. So here is the results. Just to let you know the Spi run was not optimized (no tweaks, no waza, no services stop, priotiziation, or affinity).

SPi32M @ 5.625Ghz, Mem Running 900Mhz Cas 6, NB @ 4.275.


Finally starting to get the hang of the MSI mobo

Should be a sick time if you can get the clocks up to 6 gig man

Looks like there might be something on the horizon for us nuts if you know what I mean as well

[cdawall]

what volts on the ram for that? and was just the chip on cold?

Thanks chew We will see what I can do at 6Ghz.. if I can get there :P I want sub 12min run. Will see if I have time to try tonight, or maybe tomorrow.

Umm.. what is on the horizon? Sorry.. so many converstation.. I am now pretty dense :P

cdawall. I believe the mem was at 2.3.. I think I could have done it at 2.2v.. but didn't want to have volt as a stability issue, since I hate going like 8 min into SuperPi.. then it crashes. As for the cooling for the ram.. I only have a 120mm fan on it, and whatever cool breeze from the LN2 pot.

[TurboDiv]

So any of you flashed from BIOS 1.0 to BIOS 1.3B7 directly using the M-FLASH ?

[SNiiPE_DoGG]

I went from 1.0 to 1.3B6 directly.

[TurboDiv]

I will be trying to go from 1.0 to 1.3B7 directly with the M-flash as soon as i have my system up and running. If the thing gives me an error it wont start flashing right, unless i force it to ? I mean if i get that "ID error" from a few pages back it will not continue unless i force it to ?

Very good run i sold my D9GTS otherwise i would see how they clocked

[Sparky]

3.6GHz stable. 3.7GHz, bsod, reboot, etc.... bump volts, still does it. What gives.... Ram is all stock timings and volts, but I haven't messed with bus speeds. Possible that a subtiming needs adjusted or something?

*edit* fiddled some more, I've got it priming 3.7GHz for the past hour and 45. Volts are 1.43 bios, 1.41-ish real under load. Tinkered with the CPU-NB volts, PLL volts, and the RAM PHY (I think it was) voltages a tad. Can't remember exact numbers without looking it up in the bios. Going to let it prime overnight and see where we stand in the morning, whether still going, failed, or BSOD/rebooted. Then go from there, hopefully pushing towards 3.8+GHz!

*edit 2* Well it rebooted sometime last night. But I got a few hours of prime out of it at least. Needs more tinkering. I wish it would just error and not reboot the system like that

[nicky.82uk]

can some please help me clock mine pleasessssss


this is my spec

MSI 790FX-GD70

Coolermaster V10

Phenom II X4 955 3.2GHz

Corsair 4GB Modules ddr3 1600

HD 4890

would be very very greatful once again thank you

[shadow_419]

There really isn't much to it depending on how far you want to go. You could probably hit 3.6-3.7ghz on stock volts so all you have to do is increase the multiplier and test for stability.

[nicky.82uk]

oh really how far can i go with the stuff i've got sorry to sound stupid just new to AMD thats all
