Anyone have GTX480 SLI probs with this board? Like "display driver has crashed and recovered" sort of errors during video playback?

[Amurtigress]

Hello,

It's not much, but I've been trying to get 4 Ghz stable on my previous C0 chip and again on my pretty fresh D0, and I finally succeeded. It appears that the F7P and F7R BIOSses were to blame.

With the F7 betas I kept having random calculation errors at 4 GHz, 1.31V VCore. They were appearing in my Linx runs usually after the 10th pass and nothing could get rid of them. This effect vanished completely after I reverted to F6 yesterday. IMHO even 4.2 GHz should be possible but the needed voltage of at least 1.36 feels too brutal to me for 24/7 use.

I also observed larger voltage variations under load on F7 beta and LLC2, the measured voltage rising above the set one. (1.31 idle, 1.33 load). It overall seems to confirm what other F7/D0 owners observed earlier. My chip has passed more than 100 linx runs by now without error at 20x200.

I can post a template if anybody is interested.

Nice CPU! and temps too What Vtt did u used to make it stable at 4500?

[RRunner]

Only 1.3v VTT

Have u tryed changing your Ioh voltages and what not? Changing the values a tiny bit helps..

[ABalthazor]

+1 with Klataa - those v's seem too high to me also.
also -
CPU Clock Drive ..............................[700]
PCI Express Clock Drive ................... [700]

I run these at 900 - seems to help cpu stability and pcie oc.
pcie oc doesn't seem to do that much for vc oc but it can really increase the speed of the storage subsystem - http://service.futuremark.com/compare?pcmv=333089

CPU Clock Drive at 900 really, really helps with minimum FPS on my multi-GPU 980-x equipped system. If I set it to 800 or 1000 my minimum FPS consistently drops to single digits in the Company of Heroes benchmark. At 900 the min FPS is back to where it should be - around 70.

It's my friend's setup. He keeps complaining about SLI issues constantly and i'm pretty damn sure it's not the SLI that's causing video playback issues, it's the damn board. Yeah we did tinker with the IOH but it only made things worse.

My single GTX480 runs at 900/2100 at stock 1.10V IOH happily on UD5 so i doubt SLI needs more than 1.30V. This UD7 in general is as stable as a smack addict shooting cappucino on a hot day.

[Johnny87au]

Have u tryed flashing to a newer version of the bios? I know the latest version is the R, im actually using the f7b, seems like the best bios for this board released so far!

[klataa]

Anyone know when Gigabyte will Make Official new bios? its almost 3 months and still official is F6

[Rambo87]

At the moment the F6 is the better. I can stay 4400 Rock Solid with my 980x only with that bios.

I've recently upgraded to a UD6 (from S775 asus board). One thing that bothers me though is the fact that the speeds on my intel SSD (xm-25) are much lower now. Also the Intel SSD optimizer in the intel SSD toolbox says there is an error and it can't optimize. Could it be that the speeds are lower because USB3.0 is enabled?

I just flashed lates beta bios F7r moded version, it's working fine for now. I did quick test with LinX on same settings and seams to be fine. I'm using i7 920 with LLC 2. I flashed from F7F. Only thing that bothers me for now with this bios is that my Lycosa and Lachesis lights are blinking when I enter MIT setting (voltage and current settings) in bios. I don't like it flashing like that.

Is your Intel SSD connected to the ICH10 SATA ports? Because if not there might be an incompatability between the Intel Toolbox and whatever SATA controller you are using. You could try swiching over to the ICH10 SATA ports if that is the case.

Although USB 3.0 shouldn't affect it. Theoretically!

what diffrence is with modded f7r?

[Gorki]

what diffrence is with modded f7r?

Only this one:

F7r MOD:
- Intel RAID for SATA - v9.6.0.1014
- Realtek PCIe GBE Family Controller Series v2.35

[JohnnyV]

Is your Intel SSD connected to the ICH10 SATA ports?

I have the SSD connected to the SATA-600 port with 2 raptors on the regular SATA ports 1 and 2. BIOS setting is RAID with XHD disabled.

The idea is (and I had this previously) to have the SSD as bootdisk and for my main game and the 2 raptors in RAID-0 for other games etc.

I've had much trouble even getting windows installed with this board which may be because of my 1333Mhz OCZ RAM. Found stable settings... got my 875k running and a mild overclock atm (3,7Ghz) which was 20 runs all RAM linx stable. Just the random read from crystaldisk is now only 180Mb/s where it used to be 260 previously.

edit: oops i just noticed i put this in the wrong thread. sry for that.

edit2: Just fyi. When putting SATA3 on Gen2 (??) in BIOS my SSD speeds are much higher so indeed it seems USB3.0 is affecting SATA speeds potentially!

Sam..
You got PM

Just got tow of these babies for my SR-2 build, but that's not here and trying on UD7.
Both X5650 A0-ES are stuck at x18 Uncore, but my good old B1 ES has unlocked.

The temp under Prime-Run is hinger than other CPUs, because I run out of goop. Not easy to jo-jo change 3 CPUs on the same MB.
Just got it up and running, still testing, but so far so good.

X5650 @4.0GHz(200x20) 1.21v , VVT=1.32v

[Johnny87au]

everytime i flash my bios with this board it works but always get a Checksum error 5400, have no idea what it means..

[ABalthazor]

I recently ran the DPC Latency Checker to check my system. It showed a DPC Latency spike every 60 seconds, which coincidentally is the hardware polling period set in EasyTune (I use EasyTune to fine-tine my PWM CPU fan.)

Exiting EasyTune stopped the DPC Latency spikes. So, if anyone is using EasyTune, you might consider moving to Speedfan or another alternative for PWM fan control.

[Leeghoofd]

Question : how bad is the performance hit in daily apps when you hit a DPC spike ?

[ABalthazor]

It doesn't seem to affect benchmarks, but I did notice a reduction in 'lag incidents' when playing Company of Heroes online. I wouldn't have suspected EasyTune as a contributing factor to online lag incidents, but it may have at least contributed.

[Leeghoofd]

Thx for the reply, might be worth a check

What would be the best version of BIOS at the moment? Thanks!
