Bit of help overclocking

[Monkey Puzzle]

Trying to get my Xeon 3060 (basically an e6600) past 3.6GHz, any help would be appreciated. Seems pretty stable atm at 3.6 with 1.48v actual showing in cpuz


Settings at for 3.6


CPU: Xeon 3060 (stock 2.4GHz 9x266)

Mobo: Asus P5K deluxe wifi

RAM 2x1GB GeIL 6400 ULL (4,4,4,12 AT 800), have another 2x1GB of it, and 2x1GB crucial 5300 ballistix to try if needed.

PSU: Enermax 600w noisetaker

Watercooled - currently just the CPU in the loop - pa120.2 ()with sharkoon se 2000rpm and a yate loon on) and a thin 120.2 radiator (with a 1600rpm scythe and a yate loon on), Temperatures are fine atm - 40C load at 1.48/1.472Vcore idle and 1.472/1.464 (cpuz seems to jump around a bit) Stock passive heatpipe cooling on NB atm, but have several 100mm, 92mm, 70mm and 60mm fans I could put over the NB/RAM if needed.


BIOS settings atm:for 3.6:

Multi - 9x
FSB - 400
FSB Strap -333

DRAM - 5,5,5,15
DRAM static read control - Auto
Transaction booster - Disabled
Clock over-charging mode - Auto
CPU spread spectrum - Disabled
PCI-E spread spectrum - Disabled

CPU Voltage - 1.5v (actual 1.48i/1.472 idle and 1.472/1.464 load)
CPU Voltage reference - Auto
CPU PLL voltage - Auto
CPU Voltage Damper - Enabled

DRAM Voltage - 2.1v (recommended for GeIL 6400 ULL RAM)
FSB Termination voltage - Auto
NB Voltage - 1.55v
NB Voltage reference - Auto
SB voltage - Auto
--------
CPU ratio control - 9
C1E support - disabled
Vanderpool Technology - Disabled
CPU TM Function - Disabled
Execute disable bit - Disabled
PECI - Disabled
Intel speeddtep (TM) Tech - disabled




I've tried upping the CPU voltage quite a bit to around 1.55V but it won't POST above 405FSBx9 iirc. Any ideas of what else to try? Previous owner of the chip said he got it to bench at around 4-4.1GHz, so hoping there is a bit more in this chip...

is the nb at default?

Hey Monkey Puzzle,

what speed is the DDR2 frequency?

Any chance you can slap up some CPU-z screenies showing the memory tabs please (at settings as posted above).

Hi, thanks for the reply guys - the RAM's at 1:1 , 800MHz, 5,5,5,15 - just uploading the pic now...

is the nb at default?

default is 1.4v I think. IIrc there's 1.4v, 1.55v and 1.7 v.

Sorry for size of pic:

Hey Monkey Puzzle,

I think we may need to get your memory tested above 400MHz (DDR2-800) speeds which will involve almost setting the system back to stock (9x266) and then using a combination of a memory divider with some FSB clocking to really test your memory, it's pretty much fundamental clocking proceedure and something you normally do before getting to the bit when your memory is set to 1:1 sync!

BIOS settings for 2.4GHz

• Multi - [AUTO]
• FSB - [AUTO] then [266 > > > 333]
• FSB Strap - [AUTO]
• DRAM Frequency - [AUTO] then [DDR2-800]
• DRAM - 5-5-5-15
• DRAM Voltage - 2.1v (recommended for GeIL 6400 ULL RAM)

Once that is done and working fine check out windows CPU-z to see if the BIOS has set your memory by its SPD . . if not re-enter BIOS and manually select DRAM Frequency - [DDR2-800].

At this stage your Processor will be running at stock 2.4GHz (9x266) but the memory will be running on an 2:3 divider at 400MHz (DDR2-800). You then are able to slowly add say 5MHz at a time to the FSB which will start overclocking the memory above its official spec while taking it easy on the rest of your components . . . e.g By the time the main system is 333MHz-FSB your memory will be running at 500MHz (DDR2-1000) although I don't expect you will get that far!

Download Memtest86+ V2.11 and burn it too a bOOtable CD-ROM and use that for testing your memory.

So if your GeIL 6400 ULL (4,4,4,12 AT 800) is slackened to 5-5-5-15 and given the recommended amount of juice (vDimm) you hopefully should be able to get more than the stock 400MHz out of it, your gunning for 450MHz (DDR2-900) or higher if possible!

If your wondering what it is we are doing here? . . . I want you to *isolate* and test the maximum frequncy of your RAM as it may well be the kit (or a single stick) can't run higher than 400MHz!

Memtest86+ is your friend , needs a few loops inbetween your FSB MHz bumps, any errrors will appear in red so you will know quickly if the sticks are doing well or doing bad!

Once you have your memory testing out the way you will be in a much better position to really make the mOst from your final overclock! (or indeed be ordering a new 4GB PC2-8500 kit lol!).

Hope this helps and get back to me when u can!
