speedeuphoria,do it! get it while thier hot.and you are right about them clocking about the same as the duals.this one i have seems to clock just as good as my E8500,maybe better. plus it taking less volts than my E8500 to do the same clocks.i will continue pushing it to see how much better it is.at this point though i stick by my word that this is probally the best cpu out there.

Finally started tweaking this thing and was able to get past 4GHz.

[ezaleina]

hi all.,this is my 1st 4ghz with Q9550.,i want to use this setting for 24/7.,but 1 of he core temp abit high.,is it ok for 24/7..any advice from all the pro's here..tq

Is your NB and VTT really set to 1.2v in the BIOS

[ezaleina]

Is your NB and VTT really set to 1.2v in the BIOS

yes bro.,i set the vtt 1.20 in bios.,1st i set it to 1.24.,after successfully boot windows.,i revert back to 1.20 to see if still can boot windows.,and the i'll try priming fo 15minutes..everythings fine.,only one of the core abit hot..is the settings ok bro..

guys whats the best ddr2 to to get for this UD3P mobo??? need to know asap so i can get it shipped tonight for tomorrow

[radaja]

ezaleina,very nice.and yes of course that would be perfect for 24/7 if it is stable.very low volts.i wish i could get mine down that low.great job

[bobreece]

some stupid questions=

1) is ddr2 faster better in any way to ddr3 ie 1200 ddr2 cas 44412 to 1800 ddr3 88824?

2) if my fsb is 500 is it better to get my ram to match 1:1 ratio?

[ezaleina]

tq so much bro radaja.,u always helping me for this.,btw bro.,one of the core abit highr than others.,is that ok..

I just ordered it, not sure how far it will go on a Xiggy S1283 but we'll see. As long as it goes over 4Ghz I'll be happy

You dont start to see benifit from ddr3 over ddr2 i believe until you get to around 1700 mgz, there is not a ton of difference between the ddr2 and ddr3, but when you start hitting 1800 + you get some decent benifit.

The big thing to me is ddr2 has reached its max, ddr3 has no way come close to its max yet, there up to ddr3 2133 mgz and climbing. I7 takes full advantage of ddr3, the p45 chipset and ddr3 are just not a good match, you need a x48, 790i chipset, or 17. Bob your better off getting a x48, 790i, i7 if your going ddr3, or use the ud3p for ddr2, hope that helps you.

[Jor3lBR]

Jor3lBr,
can you tell me approximately where the recommendations for the CPU Ref and MCH Ref settings are in this thread? as well as any other appropriate Bios settings are? I will only be going after a mild overclock somewhere around 400fsb, btw.

UD3P rev 1.1 PCB
Crucial Ballistix 2x2GB DDR2 CL4 kit
Intel e8400

I'm sorry I no good to help you out on Duo Cores, I don't have a dually since the E4400 I think.

So your best bet would be getting some stable templates here and pay extra attention to Cpu Ref and MCH Ref, tweak them to your RAM and CPU.

Memtest #7 errors means a bad MCH Ref setting;

If you feel all the voltages are good and you fail Prime95 in few minutes thats a sign of a bad CPU Ref setting.

[radaja]

ezaleina,mine are weird too,ive got two stuck.one wont go below 36c and the other wont go below 31c.the other two drop down to about 23c 26c when its cool enough.but above 36c they all scale pretty evenly.how much higher is your high one?it shouldnt be a problem with a few degrees difference.if your using realtemp you can calibrate them so they are the same i think?

had 790i hated it x48 mobo is not worth it with i7 being here now so will sell 790i and ddr3 and get ddr2 and EP45-UD3P cheers fot the help m8

what is the best ddr2 to get ie mhz timeings ect????

[pangingIII]

what is the best ddr2 to get ie mhz timeings ect????

i recommend OCZ Flex II PC2-9200 4GB (2x2GB) kit if you can find it.
however, you cannot expect to get tight timings out of the memory kit.

[redrumy3]

i looking to get a P45 board, since my ip35PRO died on me 2 days ago, do you recommend the ud3p or BIOSTAR TPower I45 LGA 775 ? I have Q6600 8GB DDR2-1000

[ghost_recon88]

I for the life of me cannot figure out what GTL refs to use. I see people all the way from .76v to .90v on the CPU and NB. I know it changes with the VTT and NB voltage you use, but not everyone is using the same formula for their calculations

You just have to experiment, really. People are using the usual percentages (0.61%, 0.63% etc).

I did a quick scan of this thread, and found the following sets of info for quads:

Speed VTT CPU Ref Multi NB NB Ref Multi PLL
8x451 1.2v .76v .63x 1.3 .76v .58x 1.5v
8x505 1.34v .83v .619x 1.4 .88v .628x 1.59v
9x500 1.4v .89v .63x 1.6 .90v .562x 1.5v
9x500 1.44v .76v .527x 1.6 .76v .475x 1.65
9x525 1.48v .815v .55x 1.6 .90v .5625x 1.59

That's what I meant when I said not everyone is using the same formula. You have CPU GTLs all the way from .52x to .63x, and NB GTLs from .475x to .628x

any other suggestions for ram as i carnt get hold of the OCZ Flex II PC2-9200 4GB

Look at Team Xtreem DDR2 9600 or 10400

[bobreece]

what this gigabyte board like using all four ram slots thinking of getting 4x1gb sticks

seens these thats all http://www.envizage.com/p/737926/tea...2x1gb-kit.html

UD3P over the tpower i45 any day, i have both, the UD3P is way better with quads
