GA-EX58-UD5 and G.Skill DDR3-1600 6GB issue? - Page 2

Last message on previous page:
Just adding my experience.

Im using OCZGold 1600Mhz with ex58-ud3r. CPU i7 920 d0 overclocked to 3ghz.

Double boots when mains power has been switched off.

Why don't gigabyte recognize this problem?!

So you guys no my double boot has been fixed(!!!) by flashing to the latest beta bios f7c which you can get here:

Hope this helps.

Changelog for this driver mentioned specifially fixing memory issues particularly ddr3-16000

Yes, its a beta bios - but it works great.

The issue is routed on memoery compatibility issues which runs through pretty much the entire x58 series.

I wouldn't be scared of buying a gigabyte board, they are a quality product and worth the money. The double boot thing isnt a serious issue (people are syaing it strains components but thats a bit of an exaggeration). Once its on its just like normal.

F7C stopped it for me so we just have to wait and see if it fixes it for others.

I have a very similar problem. System:

Gigabyte GA-EX58-UD5 BIOS F8f
Intel i7 920
2 x 295gtx platinum Inno 3d cards in quad SLI
6gb 2000mhz Gskill Trident Kit
4 x SATAII Seagate drives in RAID0 (intel chip)
1000 Antec PSU (True Power Quattor I think)

I can not set the memory to its default speed of 2000mhz (XMP or manual)
I can not overclock the system at all, any setting changes from detault (for CPU/Memory) makes the system hang before POST

I am getting really bad performance (Vista64 Ultimate) for this kind of system. Running at default settings (1066mhz ram speed unfortunantly) im getting 17000 score on 3dmark06 (I got higher than this with my old system which was an Asus p5Q/E8500/4gb Gskill 1100mhz ram/260GTX). Playing Microsoft FSX (what I upgraded for) is getting me around 6-10 FPS. Used to get a solid 20FPS on the old system with much higher detail settings than what Ive been trying!

Very dissapointed. Nobody has had any advice yet from Gskill/Gigabyte/Forums which has been able to help get the system working at even 'normal' settings let alone overclocked.

I have seen others with the motherboard running this CPU at 4ghz+ with no problems. Seems the only difference is the video cards and ram, so Im thinking it must be a ram related setting?

Im using a x58-ud4p board + 6x1 g.skill 1600 with an f7 bios and i occasionally get the dreaded double boot.

The only remedy i can find is leaving auto timings on cl8 increase ddr multi to 10 & up ddrv to 1.54v. This leaves me at 1333mhz or up to 1500 on a slight oc with no issues at all. I havent seen a reboot for 6 months.

If i change everything back to full auto at 1066 - reboot
If i go over 1500 with any qpi or ddr voltage increase- reboot
If i use auto + xmp - reboot

What is this? my board or ram issues? I think a g.skill or gigabyte tech should respond

I got a 400 point benchmark increase from 1033 to 1333 so id like to see 1600 some day stable. Any suggestions?

Things could be worse tho, i got a 17800 w/oc bench with 1 gtx 260 and i see the guy who posted a couple posts above me hit 17000 in quad sli.

I too have the FF code. Board GA-EX58-UD5, 920, OCZ XMP Ready Series 6GB (3 x 2GB), Dual (sometime tri) boot at cold. Message saying some type of overclocking failure and settings might not be what I started with. (Something like that).

At first I thought it was just something I was doing wrong and I kept scratching my head. I came across this group looking for something else. Guess I am not alone in this type of occurance.

I bought UD5, i7 950, and Dominator GT 1866 (7-8-7-20-2T) last week. After having the cold boot problem for about 7 days, I have spent few days on reading all kind of posts about ex58-UD5 boards, and another two days on testing my system with all kind of voltages/frequencies, it seems to me that I found solution, at least for myself.

Everything is working like charm, no BSODs or any kind of errors. XMP profile on Corsair is 1.65V DDR3, 1.6V QPI, every reset is OK, but starting after shutdown (1h,2h) was always double boot. I try all kind of BIOS versions (f7, f7d, f9e, f9h). But always the same. Even if I lower QPI voltage manual to 1.4V, 1.375V, double boot again.

But what if my QPI was still to high. So lower it again, to 1.315V. And BINGO. It's stable. No double boot. I even overclock i7 to 3500 Mhz (with turbo boost to 3700), QPI link 5600 Mhz, vcore 1.24V. NO double boot after disconnecting supply for whole night (and pressing on/off to discharge capacitors).

I don't know how to explain, why QPI cannot go any higher (at least for not suffering double boot). It must be in 0.5 V range with DDR, but I dont know does it have any connection with some other voltage?? It seems to me reasonable, because if you have very fast memory, guess you have fast processor, or at least intention to have it with overclock. I didnt try to upper vcore voltage, because there is no need, but maybe (just maybe) only higher vcore voltage will support higher QPI/uncore voltage (they both are on same silicon, logically there must not be great V difference).

I hope that some one tried f9 versions, because non of them working on me. I cannot boot XMP or manually specifying memory profile. On f7, works without problems.

Pls, comment.

So, please, comment.

Your northbridge voltage control is on the second of the "MB Intelligent Tweaker(M.I.T.)" pages, and is labeled "IOH Core" (nothbridges used to be labeled MCH [memory control hub], but since the advent of the new platforms with the on-die memory controllers, are called IOHs [input/output hub])...

I haven't followed this whole thread, but you might find some useful info here:

if you haven't seen it yet...

Well in the spirit of giving something back here is what I ended up with

My homebuild: Core i7 920 (with D0 stepping), 6GB OCZ Blade 2000MHz 7-8-7-20 Triple channel ram kit, Gigabyte EX58-UD5 (BIOS F9e), Win7, Corsair HX1000 PSU, Noctua air cooler, Silverstone TJ09 case.

Condensing about 4 hours work into a few lines

1. Loaded optimised defaults
2. Set up RAM settings using the SPD (Quick) option in the BIOS according to manufacturers specs, set DRAM voltage to 1.56V and System memory multiplier to 12.
So initially RAM frequency was around 1600 MHz

Clock Ratio started and stayed on x20
QPI ration started and finished on Auto as did uncore voltage
Set Base clk to 140
Turned Turbo mode off

This was my base setup that was stable

Then increased BCLK from 140 - 170 in increments ot 5 rebooting each time to check stability. When the RAM frequence rode above 1800. I kicked the multiplier down a notch and carried on.

The result a stable 3.4 GHz CPU overclock, memeory running at 1700 MHz

CPU core voltage rose from 35 degrees C (at 133) to 45 degrees (at 170)
VCore for the CPU rose from 1.204V to 1.36

So far it has been rock stable

Hello everyone. I'm very happy I FINALLY have a thread / forum where people have the EXACT same problem as I have ...

I have bought my computer a few months ago (june 2009). The most important specs are:
- Gigabyte UD4P with 3 x 2 Gb Corsair memory (frequency1333 MHz)
- Intel i920 processor
- Nvidia GTX275 card
- 2 Hard Disks from Western Dgital (1 green & 1 black) HD's (both 500 Gb)
- Corsair 620 HX power supply
- Antec P182

System = latest BIOS (no beta): F8 2009/05/11

Problem:
- The RAM frequency is 1066 MHz, I never tried to adjust something in BIOS (to 1333 is the frequency of my RAM!) since the PC is runnig super fine!
- HOWEVER ... once in a while the PC boots up, and the last thing I see on the screen is the memory settings (as in '1066 MHz - Memtest OK), after that the PC just reboots: power off --> fans blowing 100 % for a few seconds (as always when the PC boots) - screens shows some info and so on --> no problem this second boot.

And the problem is: PC always stable as a rock after that!

My question: Should I worry and bye a new motherboard, I don't want to change my motherboard when I have a chance that it is not, a stable as the one I have now (apart from the, sometimes 'dual boot' I have ...)?

And do the experts on this forum have a solution for this 'a bit annoying' problem?

I would also like to have a solution where I have sttings where I can run my RAM to 1333 MHz in stead of the 1066 it is running now (stable)


Thanks everyone!

PS: I hope I'm not 'hijacking' this thread - I'm an bit new to these threads/forums ... .
