Hey, I found a high FSB. Amazing what you discover when you keep on fiddling!



My old way still works better:

[Hoss331]

what NB Waterblock do you suggest for my ud3r ?
and for the mosfets are 2 enzotech mst 81 good ?

The only nb block that I know of that fits right is the EK 5.

[SpuTnicK]

Threre are also Anfitfc and Mips who has ud3/p/r waterbloks both for chipsets and mosfets
Looky Here: www.aquatuning.de

[SpuTnicK]

That's Anfitec

I'm still running bios 6 that came with my rev 1.1
Should I use another (see my sig)?

great .. i can find the ek nb/sb 5 here in italy

and what about the enzotech mst 81 for the mosfets ?

I think most of the bios's are pretty equal.

Is anyone else having problems using Memset? It worked fine with my Old P5K Dlx but with my new UD3P (rev 1.0) the "Apply" Button is greyed out and i cant change anything from within windows.

I have tried it on the F6 and F9 BIOS and i get the same issue, any ideas?

[kahuna321]

Can't seem to get past 466 fsb!

45-ud3r
q9650 466x9= 4.19g
muskin 8500 4x2g, 2.4b =1116
true w/ sythe ultra kaze 2000 in push/pull, lapped

1.35 cpu
1.32 nb

all other settings auto

tried changing all voltages, multipliers but cant get past 4.19g (super pi 1m=11.123 secs)

temps def not prob, very well ventilated case- all stress tests runs 8+ hours

waiting on new ocz blades 1200- think mem is the prob

anyone with ideas?

thx

I just figured out, that it can only be used in "Turbo" mode...at least in 6.

If you're running 1:1, you should get to 550 FSB without an issue (RAM wise).
I had to drop to multi of 7 to get above 500 FSB.

It works fine for me in standard mode on F9.

very nicely done 18 is# 1,hell youve only had the board for a couple of weeks and your already at 555fsb

anyone interested in my board or ram?

[XmikeX]

Hey dudes,

Time to defend your most-interesting gigabyte LGA775 mobos.

Check this thread out and vote for what you think is best :

Ah, alright ill check it out.

Thanks!

I must say that those EP45 are so easy to get up to FSB 500 on a 45nm quad, I just love it.

Here´s my EP45T-UD3P with Q9650 @ 500 4,0GHz and 2x2 Transcend 1800C8 @ 1600 777 21 tRD9 stable with LinX and P95 custom blend 4x900mb ram load.





and yes she passed all of them

[Hoss331]

This is what I have so far with the blades. This is a custom large fft run with 1600mb of ram selected, same as what blend uses, instead of the 8mb that large fft would normally use. Vdimm 1.92 is apparently borked on this board or bios because it cant be set, its either 1.90 or 1.94. The weird part is 1.90 gives me 1.87 actual and 1.94 gives me 1.89 actual, basically what 1.92 would.

[Ghostleader]

Looking good Hoss331

How are your bandwidth and Super Pi 32M at that speed, here´s mine at FSB 500 4,5GHz ram @ 1600 777 21 tRD 9 Turbo, subtiming are all on auto.

[radaja]

o got it to run at 9x512@4608 w/134v but it failed after 59minutes
im going to keep messing with it,i know i can get stable with 1.34v

Change your RAM to 1:1 and PL to 9

[noinimod]

Great results everyone!
Have some questions to ask. The bios vcore's set to 1.33, but in cpuz, my cpu vcore under load's reflected as 1.30. Which is the true reading?
So i got my q9550 to 471x8.5 stable @ 1.3v (cpuz), but i suspect it could be lower - i'm still quite lost with all the mch/vtt settings. I noticed that at 471FSB, my chip is unstable as hell if my mch is @ 1.3, but once i bump the MCH up to 1.32, it runs 50 rounds of LinX w/o issues.

Any ideas how i can proceed from here to tweak the oc?

Here ya go, 500*9 @ 1250 5-5-5-15 PL8 in standard mode. Ill run it in turbo later to see if it makes a difference, last time I checked it was only maybe 1 sec faster than standard and virtually no difference in bandwidth. I only have the trial version of everest so I cant post the pretty blue benchmark screen. If you really want I can post pics of the individual tests, but its does 10423 R, 10640 W, 10789 C and 49.2 L.

Thank you, much apprecieted, really nice to see a DDR2 vs DDR3 P45 comparison with a Q9650 and 2x2Gb ram and both in Windows 7 RC 64bit, if I´m not misstaken.

So 500 4,5 2x2 DDR3-1600 777 21 tRD9 does almost perform the same as 500 4,5 2x2 DDR2-1250 555 15 tRD8 with Super Pi 32M, it´s pretty close I most say and so is the bandwidth and latency.

Do you care to run some more comparison tests, we stay with the same CPU bus, clock and memory speed as in Super Pi, should be nice to have a test that responds well on ram bandwidth and latency, any suggestions.

My first run was in diagnostic startup mode with Windows 7 RC 64bit (less change to corrupt when run tests) but I did a rerun i normal startup mode to see if it was different but it wasn´t, it was within 1sec.

[Hoss331]

Im on 7201 which is probably not going to make a difference vs 7100. This is with the same settings as before just on turbo mode instead of standard. Its only a half second faster so it still doesnt seem like turbo does any good vs standard, bandwidth is also basically the same.

Nice work Hoss331. Would you mind posting your bios settings using this template? Thanks a lot!! Again Great Job!!
