Hi guys,

I've moved from a e6600 that I clocked to 3.4 with 4 gig ddr2 to a q9550 and 8 gig ddr3 which I'm hoping to get close to 4ghz as possible.

I've disable the C1E smart step stuff and set my timings on the ram. All voltages are stock.

I've sent the FSB to 350 to get this clock speed. I did try 400 but it wouldnt post.



These are the specs of my ram:

Module Size: 8GB kit (4GBx2)
Package: Ballistix 240-pin DIMM
Feature: DDR3 PC3-10600
Specs: DDR3 PC3-10600 • 7-7-7-24 • Unbuffered • NON-ECC • DDR3-1333 • 1.5V • 256Meg x 64

Do I need to raise the CPU voltage to get higher speeds?
Have I missed anything?

I ran mine at 400, if I remember correctly I had to bump up PLL and Northbridge voltages for it to be stable (I was running with all DIMM slots occupied though but worth a try).

What motherboard are you using?
 
Unless you want a permanent BAN I would suggest you remove the links to the seedy pic hosting site.
 
MB is a asus P5G41T-M

I've got it to run at 395 so close to the 400! How much should I add/run the PLL and northbridge at?


PCZ it's hardly porn its just girls in bikinis.
 
Be cautious with the voltages if you bump them up too much - on the earlier Q9550 vcore or VTT (FSB Term) too much above 1.4 would kill them (I can't remember if it was 1.425 or 1.45 that was the max "safe" voltage). Shouldn't need more than about 1.38 tops to get 4GHz on the right motherboard anyhow. If its one of the more recent batches then they can take a bit more but as a general rule you don't want to be going above ~1.4v if you can help it.

EDIT: Oh and definitely change the hosting and a warning to anyone clicking on those images in the first post the page is NOT SAFE FOR WORK. (the banner images I got were quite a bit more seedy than bikini pics - doesn't bother me personally but not appropriate if people are at work or infront of family).

Their not bikini pics.
Since when has oral sex been a bikini pic
Anyone viewing them at work could be in very hot water.

There you go. Apologies if anyone was offended I didn't know porn was there.

My current voltage is 1.304v. Shall I push it a bit more and see if she'll boot at 400?
 
You may find the board has FSB holes - a lot of those LGA775 boards did so for instance 400 might not work but 402 might work fine. You'll probably need to increase NB voltage a little as well as vcore and PLL, etc. once you get above ~3.5GHz I'd be suprised if you can't get above 3GHz with stock voltages tho.
 
Thanks mate. Could you give me some examples of what sort of voltages I should be setting for those?

I'll see if i'm in a hole too :)
 
Shouldn't normally have to adjust the SB voltage unless your going for monster clocks, leave on default.

Most of the rest of those settings anything that results in upto 1.4v should be safe enough - if you have high end air cooling then you can probably go a little above that - I probably wouldn't go all the way to max on the NB voltage unless you've replaced the stock heatsink on the NB.

Don't adjust the memory voltage - infact if possible find out what your memory runs at and set that just incase the auto setting is whacky and starts pumping too much voltage at higher CPU clocks. A lot of the performance DDR2 RAM was based on D9GMH chips that degraded quite quickly with more than a minor voltage bump.

I would also limit the PCI Express frequency to either 100 or 101 - some people find 101 or 102 work better than 100.
 
Ok my memory is 1.5 volt so I'll set that.
I'll set the PCI e to 100.
I'll set my NB voltage to 1.4?
What is the VTT voltage?
I've got a zalman 9700 on my CPU.
 
what MB do you have ?

Some thoughts.
Your memory speed is increasing with the FSB and maybe it isn't happy with the default 7,7,7,24 timings.
Try setting loose timings 9,9,9,27 for example

You can raise memory voltage above the default 1.5v.
1.65v should be fine, it was only when Sandy hit that memory voltage become a concern.

You can raise VTT a bit try 1.3 for a start.
NB voltage may need to be raised a tad also.


If possible reduce the memory multi.
I suspect though that the 1066 setting may be the lowest anyway.
If you have a setting in you bios for FSB strap, set it to 400

I never used DDR3 with any socket 775 CPU's myself.
My 775 boards are all ddr2.

Without knowing what board you have it is hard to be more specific.
 
Have a read of this thread. A lot of us put all our settings in there. You are going to need a good board to hit 4Ghz. Nvidia chipsets along with X38, X48 and P43 won't do it. P45 was the best chipset for clocking the 45nm quads.

Oops missed you were using DDR3 on there, so used to LGA775 boards that only took DDR2. Memory voltage on that setup is less of an issue than it was with DDR2 sticks.
 
I tried all the above settings and tweaking them but it would not boot.
It's strange that its super stable @ 395 but won post at 396.
