Correct settings for CMZ8GX3M2A1600C9 AND GA-P43T-ES3G?

My motherboard is compatible with this memory and XMP.

Well first off my XMP profile doesn't work, it crashes, shows up memtest errors and won't let Windows start and reboots every time I try.

That doesn't happen when its at default speed of 1333MHz

and no errors show up in memtest.

I have been just using it at 1333MHz for a few weeks because I've been so busy but I want to figure this out and get it to 1600MHz.

I have really no experience at this and have no idea what I need to do as far as settings are concerned.

What are the correct settings for this motherboard?

My motherboard is Gigabyte GA-P43T-ES3G,

Memory is CMZ8GX3M2A1600C9 DDRS 1600MHz 8GB 2X4GB sticks.

The pics are greyscale because the camera was going crazy with the blue.

Here are the pics of my current settings:

If you could tell me what each setting is supposed to be so I can be sure its not failed memory sticks :D PLEASE PLEASE PLEASE

I need these at the top of there game, I'm just about to start on some memory intensive stuff.

If you need any more info please tell.

Im in the same boat with the p43 chipset

its very hard to get stable at 1600 on the ram

Here's how you will want to run it to get 1600 on the ram though

Cpu Clock Ratio 8x

Fine CPU Clock Ratio 0.0

Cpu Host Clock Control Enabled

Cpu Host Frequency 400

Pci Express Frequency 100

Extreme Memory Profile Profile 1

Mch Frequency Latch 400

System Memory Multiplier (select the one that makes the one below 1600)

Mch Core atleast 1.25v maybe more dont go too nuts though 1.35 max

That way you will be running it at 400x8 for 3.2 ghz so you can run the ram at 800mhz (1600 ddr)

a 40mhz overclock is fine on the cpu from 3.16 ghz

Well I don't know what happened to that guys post but

I can't get it to stabilize. I took a very long time to gradually go up to it.

I overclocked it correctly and I got it stable, turned it off and it went to heck again.

got it to back up but I can't get it to stabilize D:

And btw XMP profile overclocks EVERYTHING including FSB and CPU.

And all the settings are correct.

I really don't know what to do..

Should I leave my computer on for a day or something after I overclock it that far?

And no my settings don't reset after I reboot.

For some reason my post got moved to a new thread:

http://forum.corsair.com/forums/showthread.php?t=93433

I have changed bios now to a later beta one and that seems to have helped stability. I still can't get 1600 to work reliably either. The times I have got the memory working at 1600 the system hangs before bios on a reboot. Also the system will not come out of sleep mode.

Now I am leaving my memory in the 1333 range and just overclocking the CPU. I'll post a link to my settings soon so you can see what I have done.

I have had more success disabling XMP and putting the settings in manually.

Yeah, I tried both XMP and manually.

The third time I overclocked it I turned on XMP after I OC'ed and it worked very nicely.

And as I said I turned the computer off and later turned it back on and it was a not stable.

Also my memory rating in Windows Experience index is 7.0 (7.1 at 1333MHz) A friend has DDR3 1333 and he has 7.4-7.8 or something like that.

I think thats a bit strange.

ok here is a link to my attempts at overclocking and the settings I used:

Google Spreadsheet

They may point you in the right direction

Ok I'll try that thanks!

I'm annoyed that they said the MB could be overclocked for 1600MHz memory yet it has a problem..

I know the CPU can handle it lol its a OC beast.

Ok this is beginning to irritate me.

I Successfully overclocked, ok?

EVERYTHING was STABLE!

I leave it for 5 hours, NOT ONE problem.

Memtest on each stick and both was 100% fine no errors

I turn it off and guess what happens today?

BEEP BEEP BEEP BEEP and it keeps going until it shuts off.

I already know what that means. It failed. the overclocking failed.

That happens when my pc is suddenly overclocked to fast or can't handle it.

I have no idea what is wrong with this -.-

I now have my system stable with the below bios settings.

What has made a huge difference for me is setting MCH Core(NB) to 1.3v. I was told that 8gb of ram needs that.

Also I think going to the F8c bios from F7 helped.

Is there an newer bios available for your board?

I realise that the ram is only working at 1413 but I gave up on the 1600 settings. I may go on to lower the CAS latency to 8's.

I have gotten mine FINALLY stable at 1500+

I raised the voltages as suggested on both MCH and DRAM by .2 volts

I cannot get it to 1600 no matter what I try. -.-

The memory states that it runs 1.5 at 1600MHz

WHY if it needs to run at .2 higher then wtf is up? just state the right voltages that are needed. I'm not understanding, oh well.

Never mind, the BIOS reset it when my computer turned on today...

I'll try again...

I'll be getting a new PSU day after tomorrow so maybe that will help keep it stable idk.

I just wish the stuff would just work, everything is compatible to run at that speed.

I guess I should of went with XMS or another company because these are ridiculous.

Ok I got it pretty well,

What I want to know is if this module is perfectly fine why can't it handle that speed at 9 9 9 24 timings?

I'm not trying to say there is a huge conspiracy lol and I'm not trying to be snotty but this is my first personal build.

And I don't want it to take a couple light years to respond D:

Here is the cpuz pic.

http://i55.tinypic.com/aw22op.png

So I should just keep my memory at 1333 until I get a 1600MHz FSB CPU (Core 2 Quad)upgrade?

Because it really is faster and smoother when the speed is at 1333 and not OC'ed.

Which is really *** up xD

And I think I'm going to reinstall windows again.

I reinstalled it with OC'ed mem and it is SLOW compared to the last install with 1333.

First off I am a noob. No necessarily to OCing but to Intel and this MB. There are some differences to what you are talking about. But I do not think it is really apples to oranges here so I hope you will able to help me.

I am on the same MB

I am using CPU Q8300 vs your 9550

I have CMX4Gxxxxx vs your CMZ8Gxxxx

Now I know the 8300 is no where near the power house the 9550 is but I have read a review that it will get to 3.45 stable with ease yet I seem to be doing something wrong. Granted it was on a different MB. I am looking to you for help. Any would be appreciated. Remember when you were noobs? :winking:

Oh and yes, I have been searching the entire web universe for answers. I can not tell you how many forums I have joined in how many countries. You guys are the ones I seem to understand. The postings of pictures really helps I must say.

A bot..?

If not (See what I did there? ;D) then I don't have a Q9550 I have a dual core e8500.
