Thanks I went ahead and downloaded that 0901 bios and winflash it successfully. Great improvement over stock 0812 when overclocking at least on my computer.

I have plus version with A2 revision for p45 chip and I've seen other poster in this thread as well.

Well ok, so it's not a rule but often plus has A3 and I haven't heard about non-plus with it.
btw. what max FSB can you set (not necessary stable) and with what V on NB?. I can't even get to bios post above FSB 410

[C-N]

Subscribed & read front 2 back.

Just couldn't wait for the UT P45 any longer so I'll just have to buy it too if/when it shows up.

I got the non plus version with an A2 chipset which came with 0613 BIOS so she's an old stock one but after only a couple of hours she's prime stable @ 533 x 7.5 4.0GHz with my E8500 & OCZ PC2-8500 SLI's on the stock box cooler.

Gratz!
Could you please post your bios settings or ABS profile?
How did you do that? Have you updated bios?
I still can't even post-bios at anything above FSB 410

I updated the BIOS to 0812

Every rig is different but here are my slightly sloppy setting, remember I only got this board yesterday & some of the voltages are a touch higher than they need to be.

I never got pass with 1.40 NB core (actually just more than 1.35), It's freeze at the windows loading, any advice ?

[Blackoberst]

Try changing NB GTL if you change vNB.

[DemonEyez]

Try changing NB GTL if you change vNB.

But also take in mind that NB GTL is derived from vTT, just like CPU GTL is.

I updated the BIOS to 0812

Every rig is different but here are my slightly sloppy setting, remember I only got this board yesterday & some of the voltages are a touch higher than they need to be.

....

B]>Voltage Settings:[/B]


SB Core/CPU PLL Voltage............. - 1.55v
NB Core Voltage..................... - 1.5575v

It's best to not set vNB and vCPU PLL the same voltage. There needs to be a gap between these two, or they'll interfere witch each other causing instability for the North Bridge.
So up your SB Core/CPU PLL Voltage or lower NB Core Voltage. I would prefer the latter. Take in account that - idealy - CPU PLL voltage is set 0.3v to 0.4v above vCC (=vcore)

Thanks,

I've tried your settings also tried pdf from DFI engineer linked before. Tried both bioses 0812 and 1003. Pity but no success. On anything above FSB 410MHz not even bios post. Well when I was trying 533 FSB with single RAM stick it posted once for like 20 tries.
I know you have non-plus board like me but I'm going to replace my board today for plus version.If that won't help I try with different PSU (my old one) then different RAM, then different mobo manufacturer (Asus/Gigabyte), etc... However I would like avoid so much trying

Speaking about RAM. Could it halt my FSB OC even if it's resulting dram speed is about 800-1000MHz?
I mean using DRAM:FSB divider 400/800 after rising FSB to 400~500. I tested ram only (without rising FSB) and it's stable on 1000 and 1100MHz (but it needs a bit more voltage then manufacurer specifies).

[puiu]

I guess because u use that DRAM:FSB ratio u can't pass over 410 fsb. For 1:1 raport u better use 333/667, u'll get the same thing and u will pass that 410+ fsb. Just use this setting

DRAM Speed.......................... - 333/667

[Tal Bar]

SEPTH I never got pass with 1.40 NB core (actually just more than 1.35), It's freeze at the windows loading, any advice ?
It's because you have NB overheating, maybe, with high NB voltage. I removed stock NB cooling for change original thermointerface, but find the small gap between heatsink and NB core. It sitting on washers for defend the core, but washers not gave for heatsink to have good contact with core. BTW, the cooling solution on the board not so strong and need to be aircooled for OC, i think.

I think I tried couple different DRAM:FSB ratios, but I try today 333:667 to be sure. I forgot to take the board from home for replace anyway :P

You are probably right but I've never found an instability problem with any of my DFI boards right back to the ICFX 3200 which was one of the first boards with GTL, VTT & PLL features.

My P35 has run for nearly a year with 1.55v pll & 1.57vnb.

I wouldn't recommend upping the PLL either for 24/7 use, I've hurt plenty CPU's max fsb using high PLL voltage.

My board/chip is running prime stable at 533fsb with 1.55 vpll & 1.25 CPU vcore. The same chip has run for a couple of months @ 475 x 9.5 1.55vpll @ 1.4vcore.

Ideally Intel don't want there 45nm's going past 1.25v but I guess when you overclock best intentions & ideals go out the window.

Need Help guys...

I got the DFI DK P45 T2RS PLUS along an E8600, 2 x 1GB Team Xtreem PC2 9600 (1200MHz) and a Palit 512MB HD4870 Sonic Dual Edition (the 1 with 2 fans). When I connect my 4870, I get 1 long beep...at times a few small beeps and the Diagnostic LED goes as it normally does but I get no display :@

I tried with 2 different PSUs (tagan 800W & Corsair 450W)...it worked with my nvidia 7150 but get no display with the 4870.

The 4870 worked fine on my other PC but it refuses to dispay on the DFI DK P45 PLUS...on both the PCIx slot.

I even updated to the latest (non-beta) BIOS on the DFI website through the other GPU but it still doesn't work.

Is there a compatibility issue ??? or do I need to do some jumper setting ???

PLS help me out guys...this is my 1st DFI and my cuz got it 4m Canada as there's no DFI in INDIA.

yeah I also read that high vPLL could damage the chip. It would be nice to see DFI change the big steps in the bios for this voltage. Asus for example let's you control it with much smaller steps.

Still I find vNB a bit high. The P35 is 90nm so 1.55v isn't that high, but P45 is 65nm and needs less voltage. So when you take that in account, 1.55v seems rather high. I wonder if longterm high voltage has severe effects on this chipset or not.

Yes you are right it is rather high however if you want to run fast & more aggressive then its needed for stability (at least with my board it is)

Have you tried 1:1 & slackening your RAM timings off to take 2x2GB sticks into account?
Try...

Surely I'll try 333/667 as I'm not sure have I before.
Btw. What's the difference between 400/800 and 333/667? Aren't they both 1:1 ?
My ram should do 533 on 1:1 without timings slackening. It's DDR2-1100MHz cl5-5-5-15 by default. Moreover I've tested 1000MHz and 1100MHz without rising FSB (on other DRAM:FSB dividers) and it fact RAM is stable not to mention about problems with bios-post (C1 on post-led).

Need Help guys...

I have 4870 also but Diamond manufactured. I have no problems at all so I doubt it helps. But maybe try to update graphic card bios... No jumpers settings (I know) will help here. Try also to set in bios PCIx for "init display first".

[Eldonko]

The difference is the strap, 400/800 should allow you to oc a little further with a small hit in performance.

[C-N]

Btw. What's the difference between 400/800 and 333/667? Aren't they both 1:1 ?

You are quite correct 400/800 & 333/667 are both 1:1 but they use different straps. The 400 strap should be easier to run than the 333 strap but I haven't actually tested it on this board. It wont cost you anything but time to play/try the 333 strap so IMO its worth a go.

My ram should do 533 on 1:1 without timings slackening. It's DDR2-1100MHz cl5-5-5-15 by default. Moreover I've tested 1000MHz and 1100MHz without rising FSB (on other DRAM:FSB dividers) and it fact RAM is stable not to mention about problems with bios-post (C1 on post-led).

I was referring to slackening the timings off from my 2gb setting if you were trying my exact timings as posted. My 4GB kits would not even run tRFC at 28~30 they need to be 46 + to get any joy out of them.

[GaS]

No one here did not mention anything about the amount of memory shown in Windows XP 32bit (maybe I just read too fast and slappy). Because on my Plus, with 2x2GB Xtreem Dark kit, system only recognize 2GB of memory. And also task manager reports 2 gigs of memery (in KB of course). Neither PAE switch doesn't help. So, this is the actual amount that OS can use, right? Or it is just shown false? BIOS version is A3. Before that, it was 0910 and XP showed 2.75GB.

Tnx!

Yea right,in theory but in practice i am able to hit 650 fsb benchable on air,and in 400/800 i cannot post at all

these days strap has only minor changes on board since the big one that was traditionally rolled in used to be tRD. Now that it's pulled out, the chipset strap is mostly just for setting memory dividers. I believe it also affects the phase offset applied for clock splitting on the MCH. I think instabilities that come out from these phase offsets are what causes FSB "holes" the majority of the time. Playing with GTL adjustments and timing offsets can sometimes bring you back into a stable regime but this still ends up being wandering in the dark unless you have a good oscilloscope handy.

[Eldonko]

That's funny, my board is useless with 333/666 and slightly less useless with 400/800. Yay for consistency!
