Thanks mate! It's appreciated.

Thanks mate! It's appreciated.

No problem, this is what I love to do!

Hey guys,

Is there an other possibility to fix the X1 bug on this motherboard? Now I'll have to set NB and SB voltage to a certain voltage but I need an higher NB for my mem to work at Cl4 1000Mhz. But when I do that it gets back on X1 again. So I hope that there is something else that I can do.

[mrt2]

Ok so I got my RAM and my pc is booted, yay!
Ok so currently my settings are:

cpu frequency: 370
RAM Frequency: 740
Memory Voltage: 2.15
Vcore: 1.45
FSB Termination: 1.45
NB Core: 1.45
SB Core: 1.60
CPU Ration: 9

Ram Timings: 5-5-5-15-5-35
Then 3-11-6-13

So what's the first thing I should do to try to push this ram... For the RAM frequency the next option from 740 is 960... could I try that? Or would tighter timings at 740 yield faster/more impressive results in real time usage?

[cletus_cassidy]

MRT2 - 960 would be a big jump on 800 mhz memory (even though the Crucial overclocks well). You might try reducing your multiplier to 8, setting your FSB to 401 and working your way up slowly from there (leaving the memory divider at 1:1).

[mrt2]

So would that give me better/faster performance? Or just a better overclock? I'm trying to find the fastest tightest memory/cpu settings I can and still be stable.

[cletus_cassidy]

It's slightly slower than what you have now. Running at 370 on this board is tough on the NB. Moving to 401 FSB, however, will allow you to slowly work past 800mhz on your RAM to figure out how fast you can get it while keeping it stable. Note that the internal latency is slowed down signficantly once you get past 400 FSB (moves to the 1333 step).

Chuck,

So you mean that flashing the bios through the bios itself with ez-flash solves the cold boot problem (or whatever it's called)?

What I am saying is that it is a very safe way to flash a bios. I would think it is almost fool proof.

What is the cold boot problem?

If my machine will be slower, then what is the benefit of running at 401 FSB and higher than 800mhz RAM? Are there some advantages to this I'm missing?

[cletus_cassidy]

You asked if you could jump up to the 4:5 memory divider running at 9*370, which your RAM won't be able to handle. Instead, I think you should start at 8*401 and WORK YOUR WAY UP from there at a 1:1 memory divider. Once you hit 417 you will be faster than you are now and you might be able to go higher than that and stay stable. The end result would be that you would be ahead in CPU speed as well as memory.

[eyes.only]

The bios utility in the P5B bios is a very easy and simple way to flash a bios.

What I am saying is that it is a very safe way to flash a bios. I would think it is almost fool proof.

What is the cold boot problem?

when pressing the power button, the system powers up and then after 1 second or so powers down again, and after 1 sec powers up again to continue the boot proces.

still struggling with my P5B Deluxe- what I can't understand is that it HATES 400 fsb upwards .... ! this is with a E6600.

@ 3.25 gig (ie 360x9) - 1.5 Vcore - stable - boots fine - Orthos stable

@ 3.2 gig (ie 401x8) - 1.525 Vcore - set bios -restart - fine -seems to be Orthos stable

BUT press reset and you've only about a 1 in 4 chance of it booting - and quite often you'd have turn on and off at the back to get the "overclocked failred" to trigger ...

409 upwards - and gets even worse - can take say 10 off/ons on the power to get into overclocked failed - and once at 415 I had to do a complete battery out CMOS reset !

any ideas please ?

I've tried VMCH low and high, same with VSB etc ...

I'm a bit concerned to whether its a mobo limitation or a CPU limitation .. ie have I hit a fsb wall on the CPU ? (ie why does it work fine at one frequency at 9x but at 8x but same freq - its a no-no ? - only difference is fsb is higher)

or a mobo limitation - this concerns me a bit more as if I buy another CPU at some point - I may hit the same limitation ?

just confused really -any ideas please ?

I also tried 1:1 RAM, 4:5 RAM, and I've had 2 sets of RAM in the mean-time - one Corsair, and one Crucial Ballistix - same results.

any ideas please ? or just very poor CPU wrt fsb overclocks ?

thanks, Mark.

Wow, I can hit 495fsb with my E6600 no problem at all and its rock stable.


How much NB vcore are you using?

Hey mrt2, glad to see your ram is working Why dont you PM me and I will help you get your stuff overclocked the way you want it.

[Buckster]

SLINROB - thanks - 1.45, 1.55 - all the same

my CPU must just hate high fsbs - or its my mobo - lets hope not the latter.

its probably my CPU - after-all it does need 1.5375 Vcore for 3.28 gig 0 which is pretty naff - comparitively - its a week 24

Did some cable tidying up today (and it was quite neat anyway) - and Mobo temp under heavy load went from 42 - to 33C - airflow is a weird and wacky thing !!

That much vcore for only 3.28ghz?! geeze........it probably is just your cpu holding you back.

[Buckster]

probably - not good is it!

that said - even though I only have a Freezer 7 Pro - TAT temps are about 47 Idle and 62 Load which I don't thnk are too bad considering the Vcore.

I find it bizarre when I see people with 6600s at similar clocks but at 1.35V with similar temps (same cooler)

makes me wonder whether there is more to it than Vcore ...

Well just as a comparison I am using the Tuniq Tower for my CPU cooling. I also do not consider my E6600 to be the best overclocker either, it takes 1.58vc to get 3.6ghz orthos stable but my temps are really good despite the VC.

Idle temps are 27c and load temps under orthos are just 54c. This is what core temp and speed fan reports.

Oh well, I will be selling this E6600 pretty soon anyway because in a few more days I plan to have a Q6600 with G0 stepping in this bad boy!

[graysky]

Be sure you flash the BIOS prior to installing your G0 stepping... my understanding is that it doesn't POST w/ anything below 1210.

[Buckster]

eek didn't know that - thanks for the heads-up graysky

whats the overclocking like with Q6600s and E6850s with this board like please ? OK but not as good as the P35s ?

could I reasonably expect with a decent cooler -for the P5B to be able to cope with a Q6600 @ 3 gig?

cheers, Mark.

Yeah thanks, I flashed to the 1215 a couple of days ago

3ghz should be cake for it and I expect it to at least go up to 3.4ghz and if im really lucky 3.6ghz.

[Buckster]

thanks SLINROB- sounds good

thought I'd give one last ditch overclock attempt with my E6600 @ 3.25 gig @ VCore Auto ... to see what the mobo thought the CPU needed ...

expected it to way-over-volt -so went into bios to check V readings first ..

set Vcore to 1.4V instead of the 1.5V I normally set.

great I thought ... but 20 seconds into Orthos blend -blue screen.

I thought Vcore Auto tended to be stable but gave way over-volts to what is needed ?

thanks, Mark.

Never trust the auto voltage setting.

[cletus_cassidy]

Make sure you post about the Q6600. I'm very curious about how this board performs with it (I'd prefer not to buy another MB). Thanks.
