nothing to do with oc, but perhaps someone with vista can try it out? :)

Installed this on my Vista x64 setup and seems to be working fine. Even though it says Vista x86 only on the gigabyte site, it installed without any problems on x64. However for some reason, the X-Fi MB comes up as a 30 day trial??:confused:

Could someone tell me how to get .5 multipliers? Like 8.5? Is it possible on a Q6600?

Thanks

Yes its your CPU as small FFT's are stress the cores harder than anything else related to P95.

2 Reasons.

1. Starting new job next week and won't be home for 3 months at least.
2. i7 platform sux when it comes to keeping stable.

I had it stable at 4GHZ 24/7 and 3D stable at 4.2-4.3GHZ but you get programs that randomly crash the whole platform is a disaster. Performance compared to core 2 Quad is fantastic but not worth wasting my time with. Even at stock speed some programs would crash. I will wait for board and CPU revision before i Upgrade again.

I was having a similar prob before (with my current setup) and it kept getting worse every week. Now I got my UD3P and reformatted all the prob's are gone. I asked on a different forum a while ago and was told that i had a bad windows install :shrug:.

Could someone please tell me how to set up DRAM Termination, MCH/DRAM Reference and Channel A & B references?

Is it more important to have a higher RAM speed or tighter timings? Right now I'm running 4.1GHz @ 8GB 4-4-4-12 on a E8400 (455x9, 1:1). I've seen people get faster times on HyperPi 32M with slightly lower clocks though. Just FYI, I'm using XP Pro 64-bit. For whatever reason, Vista 32-bit actually felt faster.

From my tests I get better bandwidth at higher speeds.

I don't have a how to answer but I can tell you in my efforts to get my Q9650 prime stable at 4450mhz (which I am still failing at btw) I played with most of the reference & voltage settings & found a strange thing.

The board displays the std/normal value e.g. MCH Reference = 0.760, ET6 also displays 0.760 but if with my quad you try booting with this value set to (I think) 0.766 the board wont boot. I found I needed to manually set 0.924 to get my board running prime. ET still displays 0.760 even though I manually set 0.924 in BIOS.

Which brings me to my point....... I would find the value you need to set to boot & simply test/fine tune up & down from there for each value.

I could find no benefit tweaking any of the values you are interested in "DRAM Termination, MCH/DRAM Reference and Channel A & B references" with my rig & 4 x 1GB sticks running up to 1250mhz.

Right now I'm Priming on 500x8.5 = 4.25GHz at 1:1 5-7-7-19. It gave me about a 30 sec - 1 min greater/worse HyperPi 32M score than 455x9 = 4.1GHz did at 4-4-4-12. Any suggestions? I realize that a better and/or worse HyperPi time doesn't necessarily mean anything in the scope of things, but I was just curious.

EDIT: 4.25GHz failed, but now I'm Priming with 475x9 @ 5-5-5-15 = 4.275Ghz. Got a bit better HyperPi 32M score, but still a ways off of 4.1 @ 4-4-4-12.

The reason I think its effecting my is cause I setting wouldn't work with my DRAM volts at 2.02v but then when I put them to 2.0v it worked great. WTF. So i'm thinking that with 2.0v and whatever the MCH volt was it had a good reference or termination or something. Therefore I want to know how to set them up right so I can always get a good reference or whatever it is. I hope that made some sense.

Well 500MHz (1000MHz) @ 5-7-7-19 is very loose. U should be able to run 5-5-5-15. Maybe a reason y its failing is because ur MCH volts are too low, what are u running it at? I found that when added my extra 2 sticks I needed quite a bit more MCH volts to run it stable. Therefore with 8GB...

Edit: Make sure ur ram performance thingy is set on standard.

The default DRAM Termination, MCH/DRAM Reference and Channel A & B references are 50% of the vdimm. Start from that point and go lower to tweak. If working from the ET6 and want to "move" those settings to BIOS, set the vdimm to 1.8V in bios first, followed by setting the DRAM Termination, MCH/DRAM Reference and Channel A & B references to the ET6 values, then raise the vdimm to the previous value. The reference volts will self adjust as the vdimm is adjusted.

Thanks so much :D

So say i need to run 2.4 vdimm, i'd set my DRAM Termination, MCH/DRAM Reference and Channel A & B references to 1.2?

If you boot to windows at 2.4 vdimm and 1.24 refenences and check the settings with the ET6, they will all be .9V, just as if the reference volts were set to "auto." Tweaking is done by adjusting the reference volts lower than the default 50% vdimm levels.

Interesting, why lower then 50% is better?

It's based solely on my limited experiments after figuring out how the settings in BIOS relate to what's displayed in the ET6. I haven't yet run into a situation where any of these vdimm referenced termination settings above 50% vdimm had any positive effect. If your experiences were to the contrary, please share.

Leave the ram references on auto and they will correctly be automatically set to 50% of the Dram voltage, but ET6 will report .90v even though they are really 1/2 of the Dram V.

to see if you can get a stable system with the voltage setting, if so, and with 2x1GB RAM, you can try lower MCH core and CPU termination voltages,
and then retest your overclock again, i would say MCH core 1.30-1.36v, CPU termination 1.20-1.30v, also try MCH ref. value 0.68v and maybe 0.72v (of VTT 1.20v),
for memory timings, you may want to first try setting Auto, and if you set Turbo, the board's bios will enter SPD's (usually, it will be using timing of the module when running at DDR2-800) timings and this should work ok with a good overclocking ram kit like yours.

i hope this helps.

-----------------
note-- in order to use the ET6's voltage setting value in your BIOS, for example, if you want to try my voltage setting (above),
the easy way is to first set VTT to 1.20v, Vdimm 1.80v,
and then set the other voltage and ref. settings using the value shown in the ET6 and go back to VTT and Vdimm and change the 2 values last.
----------------------------------

Thank you pangingIII, awesome help as usuall, much appreciated. :up:

Sorry for the late response, I have had some Christmas computer time off.

All my RAM sets are okey according to Memtest86+ and since I can run FSB 450 RAM 1200 CAS5 and FSB 500 RAM 1333 CAS5 without error in LinX, Prime95 blend and HCI design Memtest, I reckon there´s nothing wrong with my RAM, it most be something else.

I remembered when setup FSB 500 RAM 1333 CAS5 I first tried with MCH core 1,40v but no boot, then I tried 1,30v and it boot okey in to Windows.

Well I tried the same with 500 1200 CAS5, start at 1,30, no boot, tried 1,28, no boot and 1,26 and it booted in to Windows.

With P35 and X48 it usually was to low volt if it didn´t boot okey but with this P45 it seems to the other way around, very interresting board this EP45-UD3P.

So with CPU Term 1,28, MCH core 1,22 and MCH ref 63,5% I was running 500 1200 555 15 tRD8 Turbo Stable.

Thank you

Yes, I´m using active cooling, Arctic cooling RAM Cooler.

I have also change the original heatspreader to Nexus heatspreader.

At 2,30v@1200MHz with original Kingston HyperX heatspreader I was above 60C without fan and with Nexus not above 45C without fan.

So with 2,30v@1200MHz, Nexus heatspreader and Arctic cooling RAM Cooler, around 35C.

This is with a temp probe between the heatspreder and the PCB, this was take with my Rampage Formula Rig.

I´m running EP45-UD3P in a open bench.
