E6750 & Gigabyte P35C-DS3R Overclocking Thread

[mrfatboy]

cleverest,


I have read about this problem before. It's happening more and more. I actually just posted a WTF post over at Tweaktown to see if they can give an answer. They have a gigabyte guy there.

What version of the board to you have? 1.0, 1.1, 2.0?

I had this problem once. Here's what I did to fix it and in this order. No guarantees to you however

1) power off at power supply
2) unplug power supply from wall
3) swear, panic, swear again, pray
4) wait 30 minutes
5) power back on and it worked

I also read people using different ram, or trying just 1 stick at a time. I would also try taking out all of your PCI cards and only plug in what is necessary. Clear cmos & remove battery. If I had to guess, this board, or later versions of it have power regulation issues. BUT THIS IS ONLY A GUESS. I love my board and there are many that have this board and love it also. Quality control issue?

Good luck.

Hi Cleverest,

When you say it won't boot, how long did you let it sit after you powered up?

I had a problem when I had my Creative X-Fi card in PCI slot 1 when I was using the F5a BIOS for my board where I got stuck and it kept trying to boot and acted like it does when you set back overclock settings where it reboots itself. However it wouldn't stop trying to reboot it self and got stuck.

I had to pull out my PCI cards, short the CMOS jumper and reboot to get it to boot, then it was still doing it after a reboot and to fix it I had to clear CMOS to default values in the BIOS.

Ever since I went to the F5 version bios (instead of F5a, I guess the 'a' stands for alpha?), my board has been working awesome and i haven't had that issue. I'm also able now to put my X-Fi in PCI slot 1 with no issues.

nope, no video at all...my CRT monitor says it's fine, waiting for computer to activate it....

-----> mrfatboy,

Thanks for the suggestions, I tried unplugging the power cord from back of system wall....shorting CMOS jumper, and waiting overnight....(6 hours)...(yes I swore some too, lol) the battery and PCI cards are still in though....tried again when I woke up....nothing....just beeps once immediately when I turn it on (perhaps faster then it should beep?) then just sits fans spinning, black screen....have to hold down power button to shut it off....

Going to try removing everything....if nothing works I have no choice but to RMA this board and I really wanted to "hang" with you guys...but I'll be going with ASUS I'm afraid if this next attempt fails...wish me luck!

You have put the 2pin jumper back on correctly after you cleared the Cmos, im only asking because i did this on a customers pc and it took me a couple of hours to realise.

Back on? There is no jumper on the CMOS by default...and after clearing it with a jumper (also tried the screwdriver tip touching trick in case the jumper wasn't making the connection), any jumper is removed from the 2-pin and the system powered on...same issue...the only difference I can make at all is removing the memory (and/or video card) I get two even beeps then but same problem.....then I re-seat it all and I get the one beep again...

Stupid Gigabyte, don't they test their junk? even if I get it working, It means I can't risk overclocking this board, it's way too touchy....

There has got to be a bad batch of these boards going around. This problem is happening way too much. How high did you set your ddr2/ddr3 overvoltage?

+2 passed 9 times in memtest, then +1 passed 19 times (overnight) so I left it at +1

Jcossin,

I tried all of that....no go.....I'm rma'ing the board....this sucks....

[jcossin]

Cleverest,

Did you try pulling the CMOS battery (flat battery on the mobo) for a bit and then putting it back in?

That sux if you really did fry it. It's quite possible that it may be something besides the mobo though, hopefully it's not RAM or CPU.

I know when I had my issue it happened in the morning before I went to work and all day I felt pissed thinking I was going to have to RMA the board but when I got home I found it was all due to the X-Fi in PCI slot 1 and clearing the CMOS did the trick. I can remember one time though when I had a Shuttle motherboard that my new mobo really was bad and I had to RMA to NewEgg. They were great about getting me a quick replacement.

hey mrfatboy! sorry i not replied sooner, been working. but to your reply of my voltages. I've recently chanced my settings to standard, so no overclocking, but my voltages according to speedfan are....



speedfan

 

[paulmichaelkemp]

speedfan



hello Mrfatboy, sorry i not reply sooner, but been working. But to your reply about my voltages, here is a screen shot of speedfan.
i've set my settings to standard now. no overclocking, but if you can help me to understand it all. is much appreciated.

cheers.

 

[paulmichaelkemp]

oops, didnt think it worked the first time,lol

Regarding memory voltages, my RAM is rated at 4-4-4-12 at 2.2V. I have DDR voltage set to +.4 in the BIOS. If I run memtest at that setting, I pass. If I lower the voltage in the BIOS to +.3, I fail within one pass on memtest.

My conclusion: The BIOS is right, EasyTune is right and these other programs (Speedfan, Everest, etc) are wrong.

Hope that makes everything clear as mud!

you have the P35-DS3L. It's the P35C-DS3R that has the possible volt problem

 

[jcossin]

Ah, good point!

I guess I keep forgetting that this IS the DSR3 thread and I keep hijacking it to talk about my DS3L!!

 

[jcossin]

Well this may explain why I get some slight whining noise through my soundcard with this motherboard...

I dont know what to believe. Vdimm is set at +0.3v in the BIOS but reads 2.26v in Everest. Vcore is set at 1.456v in BIOS but reads 1.41V in Speedfan & cpu-z. Like you though, my RAM is rated for 2.1v at 4-4-4-12 & if I drop vdimm to +0.2v, I fail orthos.

Interesting article on the sound card. MrFB was on to something when he said it was shit.

In the UK components have to pass a lot more stricter tests than in the US, im pretty sure that EMI is one of em so i dont think this will effect the UK line, but saying that you might be from the UK which basically make me look like a twat so i could be wrong.

 

[bryanW1995]

vcore will suffer from vdroop, which is usually .04-.05 on a c2d.

 

[Conjugal Visit]

A little related to voltages, I guess...I was browsing the Gigabyte site site, looking at BIOS. Info seems to say that if I have the E6750 C2D (which I do) that I should be using the F4 Bios. Yet I can't find any description of the F4 Bios changes, except a mention re: keyboards. Well, I use @bios to flash my rig to F4. And while I didn't notice anything relating to more or less stability at overclock - currently 3.52GHz (FSB 440 - mem linked at 1:1 - 4-4-4-12 extreme timings) I noticed that when I open CPU-Z and check voltages at idle, that the voltage showed is significantly higher than the voltage reported when running the F2 bios.

I have enabled C1E AND EIST, and with the F2 bios, at idle, CPU-Z would show the system multiplier throttled back to X6, AND the vcore voltage in the 0.980 range. On the other hand, running F4 seems to allow the multiplier to throttle down to X6, but does not throttle back vcore. Any ideas why this might be? Any ideas as to why running the F4 bios is beneficial to an E6750 owner?

I've reverted back to the F2 for the time being, and again, CPU-Z reports BOTH multiplier and vcore throttling back at idle.

Regards,

CV

 

[5t3v0]

cv, do you have the vcore on auto to get the voltage throttling back? Once I set vcore to anything other than auto, EIST does nothing to it. If you have got 3.52GHz on stock volts then that's a very impressive OC.

Regarding the loss of functionality from F2 to F4, I can only presume that it is a bug. Worth reporting to GB support. I've contacted them a few times & they've been very prompt at responding. I've stuck with the F2 BIOS as I've seen no reason to upgrade based on the extremely thin info in the change history. I wonder if the increase in voltage reported from the F4 BIOS was real. If I could lower the vcore to achieve the same overclock, I'd be interested in upgrading. Anyone want to test this?

 

[Conjugal Visit]

@5T3v0 - stock volts? That WOULD be sweet! No, vcore is set to 1.3500v. Please refer to my post on page 9 of this thread, and you'll see a detailed write-up of my Bios settings. I've added some chit-chat on C1E and EIST and the results I've obtained with these two items enabled after overclock. Your hardware and mine, Stevo, is virtually identical - differences would be PSU, you are running Raid0, and you are running under Vista. I would imagine that you could duplicate what I've observed regarding the throttling down.

You see, I really want to continue to observe this throttle back of multiplier as well as voltage. I want to overclock - for gaming and CPU intensive work - but I don't want to leave the system running the overclock 24/7. F2 seems to give me what I want. Of course, all that is pinned to faith that CPU-Z is reporting reality. As I type this, CPU-Z reports Core Speed at 2.64GHz (FSB at 440 - multiplier reduced to X6) and Voltage at 0.963! Both values are below stock.

i just posted over at Tweaktown asking them about the f4 bios. Janus (gigabyte rep) has not responed to anybody for 3 days. Maybe he is on vacation Or the questions are too sensitive

I can only comment on the f4g bios. I'm affraid to change to anything else :Q

 

[Conjugal Visit]

@mrfatboy - I think I've read the same thread. It engendered, um, a little nervousness in me, prolly due to the language barriers more than anything else. But wasn't Janus going on about moving ppl away from the F4 bios and emailing them some special F3 bios that's never been "released" to the Gigabyte website? It was about that time that I stopped reading and started hunkering down with the F2 bios, until something compelling makes me want to stray....

Regards,

 

[mrfatboy]

About a couple of weeks ago Janus was telling everybody to go to the F3 bios which he would mail to you if you asked. This was in response to several people complaining about the "cycle reboot" problem. I think there was a mixed response because some people were having the problem with the F2 as well as the F4g.

I even emailed 2 weeks ago for the F3 and he has never responded. Maybe because the final F4 just came out. I still would have liked to get response from him. It's just common courtesy Especially when it's your job
