i think i have finally worked out the problem notice the fact we are all using 800mhz ram and goign for high FSB clocks making the ram unstable due to normally running out of voltage, as when i was running my rig @ 380*9 the ram was set to 677 and still hitting a speed of 900mhz ! 100 over stock:P not bad lol but as the max mem v my board can have is 2.08 am a bit stuck think the solution will be some 1066 ram :) letting me remain stable hope this helps a few other people?

That doesn't sound quite right;

Using either the 667MHz or 800MHz strap and the 1:1 divider, the RAM should run at 533MHz at stock CPU FSB for 266MHz CPUs or 667MHz for 333MHz CPUs. Increasing the FSB to 380 will only raise the RAM speed to 760MHz so you must be using the 1:1.2 divider to get 900MHz.

The 800MHz/667MHz strap adjustment does not affect RAM clocking other than it tells the BIOS to expect a bit more oomph to be required if you are using the higher strap. I'm always using the 800MHz strap and the 1:1 divider to get over 450FSB.
 
Hi im back again, finnaly got some photos taken of my friends bios and also managed to discover what the issue is with his board and to me the ram is locked at 1:1regardless of bios alterations. The board was flashed to v1.3 and the bios has been restored to defaults by the bios menu and hard reset by the battery the bios also shows at post as v1.3

with the settings here the machine will not post, the ram will not set through its dividers regardless of wich i use. I have tested the machine with an fsb of 230 in combination with very possible ram divider. when i set the fsb to 220the machine will boot at 1.75ghz with the ram runing at 880mhz wich is 1:1 but then ill mess around with the dividers to lower that closer to 800 by selecting the 1:1.2 and the pc still boots at 1.75ghz with a ram speed of 880mhz but the divider is still at 1:1.2 when it boots back up so the setting saved, so to me the ram dividers are doing absoloutly squat as they should and the ram is locked at 1:1. ive tryed this with geil ull 800mhz ram and some cheaper ram wich run at stock @ 1.8v so as to eliminate the fact of the geil ram being undervolted. ive locked the pci clock and unlocked it to no avail.

ram is slackend off so as to allow it to be overclocked in fear i was using the wrong dividers even though manually selecting each and every single one in sequance with each and every single FSB change.
As for system memory freaquancy i have had this set to [by spd] 800mhz and 667 but it makes no differance what so ever.

heres a couple more pages just in the hope that i have just got somthing set wrong but from what ive sene people say as to the fact of just having to drop a chip in and ramp up the FSB with the correct divider on stock settings im in serious doubt of this.
At the moment with the hope that it is somehow human error and with the fact in my mind that other people have had boards wich clock tremendously i must say that this is the absolout worset board ive seen for overclocking, ive had socket a asrock boards wich clock better and more stable than this though i think i may have just been really really unlucky.
hope you can help :(

Hi all first off i apologise if this is in wrong section.:D
I am very interested in this board very cheap ish??? and will be my first venture in to oc'ing withit. I have a E2180 and some patriot 667mhz ram. I don't really want to buy new ram as this is less than 2 months old. Would this combo be ok in this board? What sort of speeds could i see rough guesses plz. Thanks in advance.

Firstly turn off CE1 this is not required and will enable you to get a better overclock.

Secondly set your ram at 667 and setting the manual cas ras and tra etc is correct. 2.0 volts on your ram is ideal to.

Change you PCI-e and sata to liner mode too this will lock em to their frequenies at the moment your overclocking them too this will not help your overclcok. also set the ram back to 1:1 for now.

It will simply be down to what your chip will handle and maybe your cpu needs a tad more voltage?

Trial and error really but the setting above allowed me to clock my 2.13 e6400 to 2.8 and i got it to 2.9 and into windows but it was unstable so i hit my cpu limit . what im am saying is i hit fsb above 350mhz so this board will do it.

doesnt solve the issue of the ram dividers not setting the ram correctly though, theres no way a 1:1.2 divider should give the same freaquancy on the ram as a 1:1 like it does. like i say with a fsb of 220 and a 1:1 divider the ram is running at 880mhz if i leave that the way it is booting with those setting and just change the divider to 1:1.2 then it should lower the ram freaquancy to somewere around say 7??mhz (just a guestimate there) though it should lower it but boots at 220fsb 1:1.2 divider and low and behold 880mhz. fair to say any more of an oc and the ram is touching over 900mhz with that in mind there no chance of even approaching an fsb of 300 :(
 
What ram do you have?

and what is it's rated frequency?

My advise also would be to load system defaults in the bios and change thing 1 at a time ......
 
geil ull 800mhz ram, ive slackend timings up'd voltages but when all said and done the mobo is trying to run the ram at over 900mhz with anything above a 230fsb wich it shouldnt and the ram was never supposed to really run that fast, thats why there are dividers (if they work lol!)
Bios defaults have been loaded numerous times and even a hard cmos resets but it hasnt made a differance updated bios to 1.3 wich solved divider issues for a lot of people but not me lol. each setting has been changed on its own or in sequance with nearly every other setting i have tryed.
 
Mighty strange m8,

are you sure your pci-e and sata are running linear mode?

also get CPU-z and get a screeny of the memory tab this might help us out.
 
Nobody has answered this question. Is this BIOS compatible with the -S version?

I don't need a second LAN port or second BIOS.

In your screen shot you have set the RAM speed by SPD - change that to either 800 or 667 and the dividers on the front screen will then work.

Try 1:1 first.

Also - set your SATA speed to FIXED and the PCIe bus to the other option so it's locked at 100.

I don't see any problem why you won't be able to get 2.7GHz without touching anything at all. I can with my E2180. I then need a touch of Vcore to get 3.33Ghz and then I need to lock the SATA bus to get 3.6GHz. Your RAM will run 1:1 at 333MHz FSB so that would be my first target.
 
Just had a play about with dram ratios and found something interesting. Set the fsb to 266 and dram ratio to 1:1.2 and found the memory speed red in the bios as 884Mhz. Anyone else had a similar result? It seems the bios is mistaking the 1.2 ratio for 1.66. Could someone else check this?
 
after futher tinkering advise i magaed to get a nice looking overclcok now hitting just under the 3.7ghz mark :) which is shown validated here http://valid.x86-secret.com/show_oc.php?id=308589

I would really want to push 4ghz but i think the ram really ius now becoming an issue running it set as 677mhz in the bios and its clocked to 2.1 volts @ 928 mhz :) pretty good for 35 quid ram lol, any one else think of anything stopping me hitting the magic 4ghz

That's a very nice overclock for a £225 cpu/motherboard/ram package.


Switch to the 800MHz strap and go on to 500FSB. Mine loves high-revving dual-cores - 510-525FSB is about where mine is topping out, and it's my RAM, not my CPU or motherboard, that's stopping me getting 4GHz stable on my E8400.

Do you have the DRAM set to "By SPD" as that seems to over-ride the divider on the front overclocking screen. I usually set mine to 667MHz for E2xx0 chips and 800FSB for Quads and Wolfies. The issue I have with my E8400 is that even at 1:1 I'm running 1000MHz on the RAM and I just can't give it enough volts. If I had a couple of wishes available I'd be asking for a wider range of CPU and RAM voltage adjustments.

I also think that it wouldn't be a bad thing if J&W copied someone else's layout for the BIOS screens as a lot of the overclocking issues we're seeing now are from a lack of familiarity with how the BIOS works.
 
WJA96 am stuck i think its possibly due to the lack of flexibiluity to stabalise the ram i tried the 800mhz strap with a 500 fsb as u suggested but it dies and on the 667 it dies after my current fsb as the ram am using the 6400(800mhz) geil ULL seems to quite like 928mhz with its 2.1 but anything after the 2.1 volts it doesnt help am thinking some 1066 ram might do the trick?
