** Official ** Gigabyte UD3 P45 Series -- EP45-UD3 / EP45-UD3R / EP45-UD3P

[Jor3lBR]

The only thing I can think of was the XP (better then my W7 run) I didn't do anything different. Same config but with fresh XP install and defraged.

[thebluemeanie1]

How big of a difference with F4-4?

I didn't do a very good comparision but it seemed to be a little better than .1 seconds. Vista to XP is a very nice gain.

[Hoss331]

hmmm.. I think I have an old 32bit xp disk around here some where.

[kahuna321]

Finally got 4.3 stable- 50 loops of intel burn, all day prime 95 but want more

Can boot and run at 4.5, just cant pass any stress tests

Heres where I'm at now:

cpu 9x500

vcore 1.375
term 1.34
ppl 1.5
ref .848

mch

core 1.4
ref .888

Mem 333, 2.0b standard

5/5/5/15

2.12
1.06

all others auto

heres my system:

ep45 ud3r f9
q9650, lapped
true lapped w/ ultra kaze 2ks in push-pull, as5
nb, mosfets all have upgraded hs/fan
muskin 1066- 4x2g=8g ( 3g in ramdisk) w/ hsf
corsair 750w
4870x2 @800/1000
case has 6 ultrakaze 2ks, very well vented
2 wd 640g black in raid 0
windows 7 64 bit

tired of waiting on the ocz 1200 blades to come in, dunno why i cant get a good clock now at 2.0b

i know i need to do something about cooling, not in the budget atm- intel burn is tickling 90 now with ambient 28-29 here, nb 93 loaded

ive gone up, down and sideways in bios, im at a loss where to go

all the big kids can get 4.5- i wanna run it too- help!!

thx

Tried another 30+ combinations, now at the following:

cpu
vcore 1.375
term 1.32
pll 1.5
ref .891

mch
core 1.38
ref .836

higher cpu ref seems to help to a point, and lower mch ref does too. tried 1.28-1.36 term, 1.32 seems most stable of all


not the fastest super p'is, but at least passes one round of intel burn.

suggestions?

Can someone post a 1m pi close to 9.2xx @ 4900?

[Jor3lBR]

Can someone post a 1m pi close to 9.2xx @ 4900?

With a DUO or Quad? If you want a Quad I just posted one on the other page 9.21s...

[coop]

If you have your quad in can you run another? Are they that much faster than duo's? I can get 9.234 but it is not very close to 4900.

[Hoss331]

for superpi there is no speed difference between quads and duos

[thebluemeanie1]

Jor3lBR's 4.9Ghz just uses incrediblely tight timings from the looks of it.

Maybe this willl help, it isn't exactly 4900 but pretty close.

Using the F4-4 BIOS I had the time down to 9.329 at 1Mhz FSB lower.

[Ghostleader]

You guys have some really nice chips and those Super Pi runs are awesome , I get somewhat envious cause my chip do only ~4,7GHz and 1M @ 9,750.

Keep up the good work guys

[QUOTE=thebluemeanie1;3886315]Jor3lBR's 4.9Ghz just uses incrediblely tight timings from the looks of it.

5/6/6/18? 1m's are rather straight forward. A couple tenths is huge.

The best I could get at 4905:
[IMG][/IMG]

Even at 5015 I could only get 9.234

[hank123]

so Ghostleader I pmed pangingIII and he blew me off. Didnt reply. I think he rigged his memory OC. I shot him a PM again we will see if he blows me off again.

[hank123]

New BIOS:

GA-EP45T-UD3R - F7a
GA-EP45-UD3P - F10b
GA-EP45-UD3R - F10c

No info.
Seems to have new AHCI ROM.....

Thats nice nothing for the EP45t-ud3p

What do you think would happen if I flashed the ep45t-ud3r f7a bios to a ep45t-ud3p?

[radaja]

you would ruin your board

[Hoss331]

higher cpu ref seems to help to a point, and lower mch ref does too. tried 1.28-1.36 term, 1.32 seems most stable of all


suggestions?

If that board is like the P 1.32 vtt will not set, its either 1.30 or 1.34. If you select 1.32 in bios then in windows pull up ET6 it comes up 1.30. If you try to set 1.32 in ET6 it will still drop down to 1.30.

[Ghostleader]

Chill hank123, just because he didn´t answer your PM don´t make him a bad guy, maybe he´s occupied by a lot of work or are on a holiday or maybe he has a policy to never answer on PM, just answer questions in threads, maybe we never gonna know but either way, in my opinion we have to respect what ever.

BTW, how is your progress with the EP45T? I´m back with me RE and are determent to make my 2x2 Transcend to work @ 1800C8

Nobody said it would be easy. Sometimes is just a combination of MHZ and Timings that the hardware will shine, that's when less is more on those benches. But there is no manual in how to achieve that, only sweating.

Well I ca't run the Q9650 right now, my UD3P is on RMA so it has to wait. Summer ruined my Cryo-Z runs :-( Too much humidity.

I run other SuperPi's back then an always close to 9.2. Now I want to get 9.1! Maybe with the Extreme, this board is better the UD3P especially on 32m runs my best on UD3P was 9m.50s and Extreme did it in 9m.35s...

Try experimenting with the different Luna themes. The silver was the best one for me.

[coop]

I've ran thousands of Pi runs. please. Probably seen close to the same. Show me something.

Lol CooP you're so competitive

Well I don't have anything to show really, all I know I post and help others, there is no need for me to play games or hide things.

I lost my best 32m run SS but I have the half pic and I can assure you it's for real:



I will redo some runs with the EP45-Extreme soon.

[coop]

[QUOTE=Jor3lBR;3887279]Lol CooP you're so competitive "

I wish I was. Just something about suggesting that 9.2@4900 is "normal" or even 5000 for that matter. It seems a bit of a stretch. I could not even find one close. Anywhere.

"Well I don't have anything to show really, all I know I post and help others,"

I know you do. I've learned from what you have shared too.

"there is no need for me to play games or hide things."

I'm not saying that you are. I think that 1m ran in 9.219sec though is hard to believe. If someone can back it up please pm me as to what it takes. Just a question, is it possible that you were clocking up to do some runs, then came back down and in the elation of such a great run, did the screen? (I actually don't even know if that is possible) Honest mistake if so. Also, great 32m at 4860. That is easily recognized. peace.

DRAM Voltage: 2.5000V
DRAM Termination: 1.25000V
Channel A Ref: 1.25000V
Channel B Ref: 1.25000V

I've got 2 x 1GB Team Xtreem PC2-10400 and that has passed 1000% HCI Memtest so I know that is alright.

The above settings are blending at the moment in Prime 95 and so far, so good.

The CPU is watercooled and is hitting the mid 70s on P95 Small FFT's with 1.4625V set in the BIOS.

The first concern is that the CPU seems to need too much VCore for some reason. It has a VID of 1.22500.

I was running this CPU in my MFII before and could get 9 * 480 at about 1.40V actual, but on the UD3P, I need to set at least 1.4625V with Load Line Calibration enabled.

Secondly, anything above around 4.35GHz, and one core immediately fails on Small FFT's and same on Blend.

I've had the UD3P for a week and have gone through this wonderful thread and followed many templates and played with all manner of CPU and MCH refs, I've tried the stock 9x multiplier too which has the same results and I've played with the straps too.

Any input would be wonderful as to whether I can push this CPU further as I know that 4.5GHz should be easy if I can work out why the CPU is wanting so much VCore.

I don't know if the CPU just gives up after 4.35 GHz as even dropping the multiplier doesn't seem to get past that wall. I know the board is good up to past 513FSB so everything is pointing to the CPU or something I am not setting correctly.

If I play with the CPU or MCH refs, I get 0x000000124 BSODs, total system freezes when Prime Blending or immediate failures in P95. I've lowered VTT and it hasn't made any difference and the same goes for higher PLL and raising/lowering VMCH.

Cheers guys

Hey Krich, I'll see if I can give you a hand. First, I don't have a Quad so your ahead of me there. I can give you a couple suggestions you can see if they help or not. Until you get some stability at the higher speed set the ram timing to 5/5/5/15. Change it back later. The vdimm seems a bit high as well. I know that is good ram but I don't know if it needs that much esp. at this speed. For 1.4vtt, your mch ref seems high also. By a fair amount. Have you tried increasing the PLL to 1.57v when you try to boot at 4.3 or above? All these things on mine need to be "together". It takes some time but when you get things closer maybe you can get a bit lower vcore. Maybe someone with a Quad can help with your mch core or something relating to what I mentioned.

[Hoss331]

KRich,
My xeon has the same 1.225 vid so give these settings a try. I ran a quick prime to check these settings and had no errors. Also what kind of water cooling do you have, those temps seems pretty high for water with that voltage. Mine with 1.4625 bios only comes up to 60c under small fft with 25c ambient.

BTW, how is your progress with the EP45T? I´m back with me RE and are determent to make my 2x2 Transcend to work @ 1800C8

nothing. I tried for hours to get anything to post. even using easy tune i cant get ram speeds up very high. I thing the highest I got to post and go into windows was around 1648mhz. And this is on good ram that is rated at 1600Mhz 7-7-7-18 @1.9V On the bugged 3;5 divider I think i can go higher but its just total junk so no point in trying.

I think a new bios will come out. It might do the trick.


Oh and I think we might see a new bios (this week...maybe) soon. We will find out
