Q6600 Overclocking Help

Also, a bit off topic but bios related:

When i boot my system, I get a message saying Detect Drives Done, no drives found.

Why does it say this?, i have my os drive in sata 0, storage in sata 1 and optical drive in sata2

on main bios page, it says:

Primary ide master: not detected
primary ide slave: not detected
third ide master: wd150gb
third ide slave: wd500gb
fourth ide master: not detected
fourth ide slave: optical drive

Any ideas about this?

Thanks

Yeah I get this when I have the onchip SATA RAID controller enabled in my BIOS but am not actually using RAID. Just needs disabling.

ok, thanks about the hard drives, i'll post elsewhere to ask.

I can't seem to find that fsb strap to northbridge anywhere. Will it be under a different name?, I can't find anything that could be it either?

Would it be possible to take a pic of your bios where you inserted values like FSB and cpu vcore? That way it will be more clearer as you mentioned you can't find FSB strap to northbridge option. It may well be called something else in your bios. In my gigabyte bios, it is known as (G)MCH frequency Latch.
 
ok,

Here's 3 photos which hopefully will be of some use:

Sorry, can't resize them as i took them on my phone and sent them to dropbox and put the public link on here.
 
Hmm everything looks fine. Seems you don't have the FSB strap to Northbridge option then as the Bios automatically sets the Ram divider values based on your current FSB and the predefined ratios.
Can you click on Dram frequency option to display all the ram values and take a photo. I want to see what bios is displaying them.

Looking at the ram divider table on the previous page, these are all the following ratios:

1:1 2 x FSb x N = 2 x 334Mhz x 1/1 = DDR2-668MHz
2:1 2 x 334 x (2/1) = DDR2-1336MHz
3:2 2 x 334 x (3/2) = DDR2-1002MHz
4:3 2 x 334 x (4/3) = DDR2-891MHz
5:3 2 x 334 x (5/3) = DDR2-1113MHz
5:4 2 x 334 x (5/4) = DDR2-835MHz
6:5 2 x 334 x (6/5) = DDR2-801MHz (no indication in bios)
8:5 2 x 334 x (8/5) = DDR2-1068Mhz (no indication in bios)
3:4 2 x 334 x (3/4) = DDR2-501Mhz (not defined in the table)

Listing values in ascending order

DDR2-501Mhz
DDR2-668MHz
DDR2-801MHz
DDR2-835MHz
DDR2-891MHz
DDR2-1002MHz
DDR2-1068Mhz
DDR2-1113MHz
DDR2-1336MHz

I think your bios/mobo doesn't include the ratio 6:5 or 8:5 otherwise you should see the 801Mhz value aswell as 1068Mhz and this is very strange. Try setting your FSB to 333Mhz and see if you do get 800Mhz.
Again I would appreciate the input of guys with asus mobos :).
 
If I set the FSB to 333 then the options change to:

500
667
834
889
1000
1111
1334

I am pretty sure that before the CMOS reset, I could get 800 to show up. (not 00% about this though) It's odd.
 
hi guys,i hope you dont mind me jumping in.
i have been following this thread. as i am in a similar position.
i also have 800mhz ram, but i have it running at 667mhz for a 1:1 ratio

^^^ if you reset your fsb to 250. would you not see 800mhz then?
as when you increase the fsb, you increase the memory freq. as well

also is 1:1 better than 6:5?

The stock FSB of Q6600 is 266MHz (266 x 9 = 2394MHz=2.4GHz). So Bios will display DDR2-800MHz using the 3:2 ratio:

2 x 266 x (3/2) = 798MHz= DDR2-800MHz roughly

or

2 x 267 x (3/2) = 801MHz=DDR2-801MHz

For FSB of 334MHz:

1:1 will give you DDR2-668MHz (2 x 334 x (1/1) = DDR2-668MHz)
6:5 will give you DDR2-801MHz (2 x 334 x (6/5) = DDR2-801MHz)

you can use both during overclocking process as your ram speed should be at stock speed or below that value anyway; so both ratios satisfy that condition.:).

However 1:1 is ideal when your FSB is 400MHz so your RAM will naturally stay at DDR2-800MHz.

Still no idea why 800 is not showing for an FSB of 334 then?

I think it would be interesting to hear from people who possessed Asus P5W DH Deluxe and overclocked their old dual cores and whether they managed to get DDR2-800MHz for the FSB of 334MHz.

OP I think just use DDR2-835MHz (mildly overclocked ram) and run memtest program. If your pc pass memtest then you are good to go:).
 
might be worth looking on cpuz when your in windows to check your real ram speed, some bios'es do go odd/quirky.

other option is to go for 400fsb
7x400 will get you 2800, 8x400 gets you 3200

im running at 3600 at the moment with 9x400 :), its watercooled
 
I'd go for the 400x8 tbh, just about guaranteed with most Q6600, usually 1.3-1.35v in my experience, my one golden chip did 3.8Ghz on 1.4v though, 3.2Ghz was a doddle at 1.15v :D

What was the VID? Afaik FSB of 400MHz will stress your northbridge a lot more than FSB of 334MHz and you do need to up the northbridge voltage aswell for stability.
 
I actually cannot remember, i do know it was nothing especially low, sold about a year now!

BTW, did not realise the P5W DH Deluxe was a 975x chipset (i was running Bad Axes in those days) .. this might be problematic as the chipset isn't the best overclocking one around and a board of that era might be a little hard pressed on the voltage regulators with a Quad + that chipset and quads don't OC well if memory serves me right. Test the stability of 3GHz before proceeding, i'd make an educated guess that 400mhz is a no go with that board and a quad, lots of 975x boards i had barely made 380MHz with a dual.

I thought that P5W DH Deluxe was only compatible with 65nm core 2 duos like E6600. Iirc I read my brother's P5W DH Deluxe mobo manual and there didn't seem to be any mention of core 2 quads compatibility. I guess Asus must have updated the compatibility with bios update. If this is the case then it is a weak mobo for core 2 quads.

Edit: Op here is a link to P5W Dh Deluxe thread

Yeah it was even updated to run 45nm quads, though reading about the net that is sketchy at best. Definetly a weak board for any quad. Though saying that i run a Q6600 @ 3.4Ghz (378x9) with 4 sticks RAM for 4GB@ 4 4 4 11 on a clients machine with a DS3 965P v 1.0 which is another old school board that really should be used to oc duals only :D, has been going strong since the G0 stepping came out, so miracles do happen lol.
