I have been trying to overclock my system fro a while now and cant seem to get past 2.74ghz. I have searched a lot of boards and see that the processor and motherboard are able to overclock fairly well yet I cant do it.

My current setup is...

CPU: e8200 @ 2.74ghz
Mobo: Gigabyte G41M-ES2L (latest BIOs rev.)
RAM: 2gb Kingston RAM (5-5-5-15 @ 2.0v) single channel (FSB 1:1)
GPU: Sapphire 4850 512mb
PSU: Thermaltake W0070RUC (430w)
Drive 1: Western Digital Raptor 36.7gb
Drive 2: Western Digital Caviar Green 750gb
Monitor: ASUS MS202N (1600x900)

If anyone has some insight on what I can try would be great. If you need more information from me please let me know.

Thanks,

Siege

you read the guide? http://www.tomshardware.com/forum/240001-29-howto-overc...

You did not mention cooling.....I also have to say that PSU is a little iffy in both wattage and quality. Cutting it close with the 4850. Standard DDR2 800 should run 5-5-5-15 at 1.8v. Is it overclocked? If it is designed to run 5-5-5-15 at 2v that could be holding you back.

Can you list the settings for me so I don't have to do the math? I'd also run CPUz to make sure the memory is at 1:1. Low overclocks are nearly always the result of the ram being ran to fast.

I am using an Arctic Cooler Freezer Pro 120mm.

Currently CPU is set to 343x8 = 2744, RAM is running 1:1 at 686x4.

When I 'load optimized' in the BIOs it sets the RAM to the boards default of 6-6-6-18 @ 1.8v. The specs on the when I purchased it actually show it should run at 5-5-5-15 @ 2.2v.

How much are you trying to achieve? Are you on stock cooling?

The ram is easy so I'll mention that first. Jedec standards call for 1.8V to be the "official" voltage for DDR2 memory. When you load the "optimized" values its reading the chart on the ram sticks and loading official settings. You can get your timings down to 5-5-5-15, but you have to up the voltage to 2.2. Its up to you either way, it shouldn't matter for your overclock. Just make sure you run it at 2.2 if you go for the 5 timings. Your ram isn't rated to do 5 timings at 1.8v.

As for your overclock, have you tried dropping the multiplier? I'm wondering because you have a G41 board and they aren't known for overclocking. Drop the multiplier down to x6 which should be as low as it goes. Start upping the FSB until you can't do it anymore.

Edit: Forgot to ask, whats the Vcore? By dropping the multiplier you shouldn't need to worry about this yet but you might need to for the final OC.

To be honest I'm not sure how far you'll be able to OC. A G41 board with RAM that needs 2.2V to hit CL5 timings isn't a good setup. Try to figure out how high your board can hit and we can take it from there.

4745454b: Will it make a difference if I run my RAM at the boards default of 6-6-6-18 @ 1.8v instead of going to 5-5-5-15 @ 2.2v for the overclock?

I have not played around with the multiplier much. So I should take the multiplier down to 6 and then do small incremental bumps on the FSB in order to see how far I can take it before the default BIOs takes over? I dont know what the Vcore is at right now. I will have to check when I get home.

Raidur: At this point my main goal has been to reach 2.75ghz since I cant get it over the 2.74ghz mark. I wouldnt mind taking it closer to 3.0ghz if possible. I am currently using an Acrtic Freezer Pro 120mm HSF.

Appreciate the help guys.

It shouldn't make any difference on the ram. Its been rated to run at 6-6-6-18 if you use 1.8v, or 5-5-5-15 if you use 2.2v. Its generally a sign of cheap ram however. Mine is 5-5-5-15 at 1.8v. I could probably use 4-4-4-12 if I upped it to 2.0-2.2v. For OCing attempts and to rule your ram out as a possible problem you might want to run 6-6-6-18 with 2.0-2.2v. Also, make sure it doesn't go above DDR2-800. You should still use CPUz to make sure your ram is at DDR2-686 like you think it is.

It runs stock at 333 x 8. You should be able to keep it at 8 and bump it up to 400MHz giving you 3.2GHz. Nearly all C2Ds can hit this. If your ram is 1:1, then it should be at DDR2-800. You have 45nm CPU, so 4.0GHz might be possible. 3.2GHz should be a walk in the park. The only reason I can think of as to why you couldn't would be the G41 board or the poor memory. Use the right divider however and the ram shouldn't play a part in this.

Alright. So I tried doing what you said with the RAM. I did verify that it is 1:1 and kept the voltage between 2.0-2.2. I have not been succesful in overclocking even when lowering multiplier and going up incrementally. I guess I may just be screwed on this setup. Im guessing the RAM has something to do with it although it is Kingston HyperX, yada yada. Or maybe the G41 board is garbage.

If you've kept the slower timings, upped the voltage, dropped the CPU multiplier and it still won't go higher then 343MHz then its probably the board. Still some things to try.

Can you change the PCIe frequency? Try it at 100, 105, and 110MHz. Also, try upping the northbridge voltage. That might help as well.

dont change the pci-express frequncy. it will damage your grpaihcs card.

Only if you change it wildly or up the voltage a lot. Mild overclock no higher then 110 hasn't hurt anything from what I've seen.

Your motherboard is the limiting factor. The G41 chipset is an "economy" chipset. It's unlikely that you will be able to push the FSB freq much past 333 MHz.

Lowering the multiplier won't help. That would require and even higher FSB for the same core frequency.

The G41 is not a bad board if[/f] you are using it with a first gen Core2 CPU with a 266 MHz FSB or one of the economy CPU's such as an E5200 with a low stock FSB and a high internal multiplier.

A Wolfdale CPU at anything other than the stock speed is not really suitable for a G41.
