Check my E6600 overclock.

Jimbo · 15 Aug 2006 at 17:41

Well I have an E6600 @ 3ghz on a Freezer pro 7 cpu cooler, motherboard is an Asus P5W DH Deluxe. RAm is Gskill 6400 NR (PC2 800).

I have the following settings.

Ai Overclocking Manual
CPU Freq 333
DRAM Freq: Auto
Performance Mode: Turbo
PCI Express Freq: 101
PCI Clock Synch Mode: 33.33
Memory Voltage: default
CPU VCore Voltage: default
FSB Term Voltage: Auto
MCH Chipset Voltage: Auto
ICH Chipset Voltage: Auto
Configure DRAM Timing by SPD: Enabled
Hyper Path 3: Disabled
DRAM Throttling Threshold: Auto

everything seems lovely and stable and im benching a little on super PI and Go-Orthos without any crashes - yet.

Problem is though I cant seem to set the Ram at 6400 speeds. It says its running PC5300 at the boot. Can anyone help?

I've not yet had a chance to play with a Conroe, but I notice you have the DRAM Frequency set to 'Auto'. Presumably this is the RAM divider which you should be able to alter to allow the RAM to work at a higher divider? See what options you have under that setting and have a fiddle

Jimbo · 15 Aug 2006 at 17:56

Can do, but it just changes from Dram freq - to something crazy like DDR 867mhz or something? if I put an fsb of 300 it will let me choose 800mhz. :confused:

Well your FSB is only 333, so depending on the divider selected it not at 400. So no 6400, select the next speed up, it'll say 833 and is the 4:5 ratio. You have a few things to change if you want to go a lot higher

Thanks mate, I just want a 3ghz overclock and I'll stay at that. I want my ram at 6400 though.

Nami · 15 Aug 2006 at 20:04

I assume that the DRAM frequency is changing the divider - basically the ratio between the FSB and the RAM frequency. As you increase the FSB, you will increase the RAM speed as well. Changing the dividers lets you customise the RAM speed to suit your overclock.

If you choose the next setting down from 867Mhz, you should be well within the rating for your RAM. That RAM is also probably capable 867Mhz but take that from someone with experience of overclocking the G.Skill and not from me

Excellent I'll try this thanks.

Fair enough, just put up the divider, its a small overclock on the ram. I'd think its good for that, maybe set the memory voltage yourself, not Auto, 2.0v for NR.

The next setting down is 1:1 667 and way to low for good ram like that.

O have just selected 833 and I have booted into windows fine. Although my board done some strange things and Im not sure if its due to the overclocks? It turned itself off and back on again after I selected save and exit the bios.

Will try some benchies to see if im stable. If not I'll up the volts on the ram.

Once your past the stock settings they do that. 2.1 on the ram is ok, but I put a 50mm fan on mine (chassis connecter) when I overvolt ram. Run S&M memory checker and see how hot they get.

Just in case you wanted a little more adventurous overclock. I'd say 3.4 is easy with your setup, keep an eye on temps, but the settings may look like this:

Ai Overclocking Manual
CPU Freq 377
DRAM Freq: DDR2-754
Performance Mode: Standard
PCI Express Freq: 101
PCI Clock Synch Mode: 33.33
Memory Voltage: 2.0
CPU VCore Voltage: 1.425
FSB Term Voltage: 1.3
MCH Chipset Voltage: 1.6
ICH Chipset Voltage: 1.05
Configure DRAM Timing by SPD: Enabled (I get better results setting manual, yours is 5-5-5-5-15 or even tighter, other do better with SPD)
Hyper Path 3: Disabled
DRAM Throttling Threshold: Disabled

Thanks very much Fornowagain, I might be tempted to try that lol. I just played Half Life 2 episode1 to test stability and it seems good. I have to say its the most awsomely smooth and soo fast, everything is maxed out and its just a pleasure to have performance like this.. im stunned.

Motherboard temps got a bit toasty at 45c but its fine.

Those volts above would be safe? Im just worried about causing more heat, although it wouldnt kill the cpu I doubt it would just shut down anyway.

Like I said, keep an eye on the temps, but you won't kill it. It'll just start to throttle back, there are better coolers around if its a problem. The voltages are medium settings, loads left to go, you may need a bit more or less. Make sure everything is off that you don't need. And that includes, DRAM throttle, hyperpath, C1, CPU thermal control, virtualthingy, Max CPUID, speedstep. With the fans on your chipset ICH&MCH to max won't hurt.

I have this exact problem with this board & was wondering if I was the only one. While the FSB will run up to 400 MHz or so, the board powers off after setting bios changes beyond 315 MHz.

Also, a restart then will result in a rather dodgy powercut to the system rather than the usual graceful one with all the fans on. I'd love to know what the experts on this board, like devious and the like have to say about this issue. Its worrying me as I have six expensive hard drives connected to this board & I don't like the board just pulling the plug on them during restarts and resets. :confused:

Yes the board powers down and cold boots once your past the standard settings. Not good for hard drives and there's no settings to change it. Sorry
