Hi All,

Anyone who may have this conifg and overclocked this chip..Id be greatful if you would care to list the required BIOS settings for the above config in order to overclock to 3.7?

I don't have the combo but have had similar in the past. What I'd do to start is just leave voltages on auto and change fsb to 1333(333) and see if she boots up. Make sure you keep your memory as close to spec as possible. Best to boot up at stock speed with voltages on auto first then go into bios and see what they are and write them down.

Most of the time mb's overshoot voltages on auto when overclocking but is a place to start. If bios has a normal option available you could lock all but vcore when you try it. The vcore you'll have to play around with. Make sure you keep an eye on temps when stress testing.

Change to above. Make sure you keep memory in spec and monitor temps during testing. Vcore on auto is ok to start. Lock other voltages to normal if available.

Hi,
Super...best result yet. Now, to assist see this imageshack of CPU-Z and Core Temp.

PC Health Status before oclock:
VCore 1.316V
DDR18V 1.920V
+3.3V 3.344V
+12V 12.048V
CPU Temp 34*c
Curr CPU Fan 2137 rpm

Please advise on anything Ive left out and if you think it might be worth going for the 4ghz mark, or even a little higher than current state? If so what next ? Have I provided you with all required info if not please advise, I think I may not have included all RAM info?, its Crucial.

Current V Core 1.344, Intel states 1.36max...how does this look to you?

What kind of cpu cooling do you have?

I'd suggest stress testing good at current overclock before trying for more.

You could use intel burn test,occt,prime95 but make sure you keep an eye on loaded temps.

 

[Berne]

Hi,

I stopped test P95 10mins into it, saw tray temps 71+70*c respectively.

Should I have, please advise? What should I be looking for on the temp side at this stage?

What CPU cooler are you using? Looks like your at your thermal limit under heavy loads.

It's possible that you may be able to drop your vcore and stay stable still. Have you tried taking control of vcore in bios? Still on auto? To test stability quicker use intel burn test to start. Just use default setting on it. It'll error out very quickly if not stable. Then try prime or occt.

 

[Berne]

Hi Kenmitch,
Some magic advice there. Im now getting an idea of what ocing is about. I tried lowest Vcore to get stable state but temps are too high so sitting at 333ghz + 1.3375. SDRAM is way too high though showing 505mhz for
DDR 2 800 PC2-6400, and I dont know how to lower in BIOS, any thoughts?

Resolved to stick with 3.7 @68*c for a shortime, but aiming 65*c with better cooling.

All the best,

Berne:thumbsup:

Once you get a better cooler you should be fine.

I don't think that dual core needs THAT much voltage. I can post stable 3ghz at almost 1.2V on a 45NM QUAD. A dual sub-4ghz shouldn't need more than 1.3V at all.

Going lower in voltage will make great returns (much lower) temps at load and idle.

Cooling
Hi,
With new F Pro 7 cooler.
FSB 337 gives 3.7ghz , Intelburntest 'Standard' states High 80 ( seems v.high to me, perhaps not though? ) Low 40*c, passed though? P95 initials are passing.

Sys Volt is AUTO, correct Scholzpdx defaulted to 1.287v .

CPU MEM states:
DRAM Freq 500mhz
FSB DRAM 2:3 all are 1.8v DDR2-800 PC2-6400

I am quite pleased with the additon in cpu speed, but would like guru view on 80 High? Wolfdales do powerup well.

Berne

NOTE: 80 is HIGH but thats 100% test...Low is 40 so stable around low 60's good enough from 2.9 to 3.7ghz.

All the best thanks to all assistance.

You're getting 80C temps now? Thats a little over my comfort level, but i only have any experience with 775 quad core, but those are supposedly much harder to OC.

Its good you changed ram frequency. If you are still going over the PC6400 spec you can always raise voltage a little (within normal ranges) and loosen up timings. I am guessing thats what your stability issue have been caused by. Running ram above spec at stock timings/voltages is a stability nightmare.

I would loosen ram timings a lot and then see if you can post at 1.2V or less with the overclock to see if thats the culprit. of your stability and to see if you can lower temps.

 

[Berne]

Hi,
Yes I suspected RAM was not set correct, thats why I posted same. I am asking for step by step tweak to ensure best RAM spec?

I believe you don't have your memory/FSB latch on the right setting. With Gigabyte it is known as the System Memory Multiplier in the bios. There should be 4 different settings. 2.00, 2.66, 3.33, 4.00. You should go with the lowest possible when it comes to overclocking at the moment. Mine comes with an A,B,C and D setting for each speed. I was told to stick with D and I have it set to 2.00D with no issues. I have read that your board only goes as low as 2.66, so lets go with that.

You have the G31 Giagabyte chipset, which has a bios similar to the P35, which is almost identical to my P45.

Overall you should try and keep the memory spec below 800 if at all possible. If you go above, I would loosen timings before adding any voltage. Maybe 7-7-7-25-55 would be a good batch of timings if you are inching towards higher clock speeds.

So, here's some bios option i'd try if I were in your chair.

CPU Clock: 11x
CPU Clock Control: Enable
PCIe: 100
CPU Host: 333
Performance Enhance: Standard
System Mem Multi: 2.6
System Voltage Control: Manual (I believe that's the wording, I don't have your board here)
CPU Voltage Control: 1.27V (approximate)
DDR2 Voltage: 1.8V (stock, isn't it?)

With these settings, your memory should be running at 886mhz or so (DDR spec 443). You will want to loosen your timings to at least 6-6-6-18 and so forth. If they don't post stable then loosen again to 7-7-7-25. If these aren't stable, I'd look around and see if people run your exact ram with more voltage. 2V seems safe, but I'm not advising that unless you are totally sure it can run well with that voltage. I can run my DDR2 800 @ 925 at 2V, but we don't have the same exact ram.

I hope this helps some. Let me know what memory multipliers you have in your bios, your exact ram (newegg listing would be great) and your current stable success.

Edit: You are running your ram at a 2:3 spec, which is even better. If you can get any lower (2.00 perhaps?) , take that route. I have a bad feeling your ram is going to be holding you back, just as mine is.

Hi,
Ive tried those settings but all failed to POST. My best results are when I set System Voltage to AUTO this way POST is always fast, You asked about Sys Mem Multi options well I have 2.0,2.5,and 3.0, but having tweaked all over the BIOS Im inclined to stick with the current AUTO setup, yes I may get a little more if I tweak much deeper but Ive no
need to. As far as timings are concerned I dont see any area to tweak even if I wanted so I can only assume they are set to AUTO also?

There is a good Utube video @ Overclocking the G31M-ES2L, it will help you advise issues I cannot comprehend. Im confused so if you want to ask one question at a time I will reply with one answer at a time.

The only thing Id like advice on is ...after viewing my attachement...are my Memory settings dangerous or unsafe to my Mem or CPU if not, Im happy to leave them as they are.

Thank you for assistance to date, reply when time permits,

They're not unsafe to your CPU or MEM per se, but they might be dangerous to your data. I would be surprised if you could run DDR2-800 at DDR2-1010.

Have you stress-tested at all?

 

[Berne]

Wow, great you read your experienced reply thank you. Yes I 'attached' the pass notice from Intelburntest in a previous post, and P95 gives passes regularly, but P95 was in truth only 3 hours or so?

Awaiting you advice and what exactly I should do to safeguard the issue, with 3.7ghz from 2.9ghz?

When time permits,

Berne

 

[VirtualLarry]

I would run Memtest86+ (note the plus, that's important) for 24hr, see if your memory is stable at that freq. Some people suggest multiple instances of HCI memtest, but I've never used that one.

PS. Any serious stress-testing should go for 24hr. Three hours of Prime95 doesn't mean all that much, sorry to say, as far as long-term stability goes. It does mean that your overclock isn't obviously unstable though.
