AA8XE Fatality

[maneshu]

I'm having problems using the multiplier of ddr600 in this board , i've got a pair of OCZ PC4200EB Rev2, my cpu is a 640 and it is stable at 41xxmhz maybe a little more, the problem is that i can't pass 245FSB with ddr600 multiplier, can anyone help me?please :(

[ukveld]

try the brand new 1.4 bios ;)

[maneshu]

already used it and it didn't work for my problem...
is there a solution?

[maneshu]

1. Fixed minor wording issue when CPU with 2M L2 cache is installed.
2. Change the adjustable FSB range to 500MHz.
3. Change the default setting of "Execute Disable Bit" to "Disable".
4. Add "C1E Function" control item.
5. Fixed the issue that system may hang when SATA port 4 in used.
6. BIOS compiled date: 03/23/2005


what's the C1E function?

[ukveld]

I haven´t tested the highest memory multiplier with overclock because my mems suck :P at default works great...


Found this at toms hardware about C1E...

The Enhanced Halt Mode C1E includes the following changes:

* The VRM specification was upgraded from 9.0 to 10.1.
* The PROCHOT (Processor Hot) signal is used to have the CPU reduce the core clock to 2.8 GHz. This is triggered by the idle task, and also causes the core voltage to drop from 1.4 V to 1.2 V.

Using C1E requires a motherboard running a suitable BIOS version, and an operating system supporting the feature. In the case of Windows XP this means SP2 is needed.

Due to the clock speed and core voltage changes, the C1E mode is much more efficient the older halt mode. We measured as little as 16.5 W minimum power required in idle mode, which makes the whole P4 Prescott family for Socket 775 far more attractive than ever before.

The C1E feature will be available for all Socket 775 Pentium 4 processors. However, be sure to check the SL-SPEC number on the processor box before buying. We put together a short list in this article; please check the corresponding page for details.

what settings are you using?
i´m not @ home and this pc doenst have msn (mandrake;))

[maneshu]

at default it works great too...
i'm gonna check my settings and then i'm gonna post it here...

[maneshu]

i was trying to use the multiplier again with 2,3vdimm, but it crashes, i even tried in single channel, in the other slot and it didn't work... :(
HELP...

[maneshu]

up :rolleyes:

Just got my Mushkin memory... managed to get 6:3 up to 255FSB so far(resulting in 764 memory clock) , will test further, try maximizing you dram and 1.75v nb voltage.

[Xassius]

Never use 3:4 or 2:3 dividers with DDR2 if you can do 1:1 at 3-2-2-x. Even at the same FSB and same 3-2-2 timings, 3:4 will only have a very marginal gain over 1:1. But chances are, you won't be able to do DDR2-800 at 3-2-2-x timings (without the right Micron based ram and voltmods). And DDR2-800 is achieved via 3:4 with 300mhz FSB. MOST if not all prescotts can do 4200mhz (300 x 14multi) or close there with good air cooling at least. THUS, unless you can do DDR2-800 at 3-2-2-x timings, OR you simply can't unlock the cpu multi (or any other reason that you can't get a decent high FSB)....1:1 is the way to go.

i can't boot with cas3... even at default...

just one correction...it was with 2:3... :D
there isn't any 6:3 divider. :p:

how do u change the multi on a 640 cpu so its at 14x in bios and also in windows....
i ave a asus p5ad2-e and i can only get benefits of the 14x multi in windows, so if i try and boot 300x14 my system wnt boot cos bios is clockin it as 16x300 :(

if you have the latest bios, 1004, on the CPU Settings you have one Option called "Intel SpeedStep Technology".
Just select "Minimum Speed" and 14x multi will become efective on bios.
That works with me! :D

ive done that, but the bios, altho shows its usin 14x multi, the clocks still represent a 16x multi... e.g 16x250 = 4ghz in bios then when i load windows clocks go down 2 3.5ghz and stay at 3.5ghz. :confused:

[portuga]

It's a bug, don't worry with that.
In my 640, when I am on default, 200fsb, with 16x it shows 3.2GHz and with 14x it shows 2.8GHz at all time.
but when you start overclocking, there is a bug that shows you the speed with 16x, despite you are with 14x.
But effectively, you are using 14x all the time. :banana:

There is also that bug on Memtest, that shows you incorrect speeds almost all the time. :confused:

[ukveld]

man... can´t make it rock solid @ 266x16 that will be my goal now :) 4.27EE here i come... (myb i´ll need WC :stick: ) how are you ramwise?

[maneshu]

my mems suck :sick: , i don't know what to do anymore, they don't boot with cas 3 even at default, and i can't use the 2:3 multi... :mad:

Mayb there faulty mate, i ave 2x 1024 sticks of ocz 4200eb and im runnin 3-2-2-1-2 @ 666mhz with 2.2v im gonna try lower the voltage c if it still runs with 2.1v :)

ocz ram runs great, but the fatal1ty didn't do the same!
with the new bios I can't run fsb 300 to 313!
with the old one (1.3), I can run it till 313 mhz (but not stable, :dammit: board)!
my opinion is that the fatal1ty isn't as great as it is presented.....

asus p5ad2-e, atm im avin trouble clockin my 640 cpu, i cnt seem 2 even boot into windows at 4.2 (263x16) the only overclock im stable at is 250x16 = 4ghz with only 1.425v. ive even used up2 1.55v to try and get 4.2ghz into windows but still no luck, cnt help but think its sumthing else holdin me back?? :(

im usin watercoolin and temps are around 33-35c idle. there are alot of settings in the bios which im totally n00b to, can any1 give me any advice to y they think my cpu cant go any higher?

only thing i can think of atm is my psu (tagan 480watt) so ive orderd a pcp&c 510 SLi, that should be with me in a weeks time.

[portuga]

shigs, what memories have you got? OCZ?
can you boot with the 2:3 divider with this board? I can't... :mad:

ive only used 1:1 / 3:4 mate
http://img91.exs.cx/img91/9695/ocz0so.jpg

in my case would 2:3 = ddr2 750??

oh and btw its 2x1gb ocz 4200eb, i brought em off the owner of the review site driverheaven.net, there the pair he used for his reivew :D

[Entsafter]

muha 3-2-2-1 what a bug ;-)

[portuga]

muha 3-2-2-1 what a bug ;-)

well, I don't know if at that speed it's a bug or not...but Tras 1 is perfectly possible.
I've ran my system with 3-2-2-1-2 perfectly :D

[shigs]

its not a bug at all :D

[Entsafter]

sry, but I can't believe that!
I've asked ocz and they told me that Tras 6 is possible with a lower frequenzy but NEVER Tras 1....
That't technical impossible....

[portuga]

in the beginning I thaught it was odd also.
than I tried and it worked well...3-2-2-1-2.

now i'm at 280FSB 1:1 with 3-2-2-4-2 timmings and it's fully stable.

[maneshu]

i'm with cas 3 right now with 1:1, at 265FSB, portuga your cpu is stable at 280FSB??

[ukveld]

maneshu can you change multiplier on bios?

[maneshu]

no, i only have the EIST Support- Enable/ Disabled and enabled or disabled it's the same thing the multi is always up and down...

[ukveld]

i must try it :) didnt knew what that option did actually

[shigs]

does any1 kno any bios / chipset tweaks for either motherboard p5ad2-e / aa8xe.....?

also wat do u guys reccomend safe 24/7 voltages for my 640 cpu on fairly high end watercooling system??

shigs

[maneshu]

i don't pass 1,5 vcore, i have 38º in full load...

[shigs]

cooling?

[maneshu]

H2O :D

[maneshu]

one question,
is it possible to make raid 0 with 4 drives?
i'm trying to do but it won't let me to select the 4 drives only 2 drives ...

[Entsafter]

i don't pass 1,5 vcore, i have 38º in full load...

watertemp @ 25°????
with a normal watertemp between 30 and 35° your cpu temp is at least 45°....
cpu block: delta T: 15-20 °
radiator: delta T: 3-5°

pls measure your watertemp ....

yeh my load temp is about 42 / 43c

[maneshu]

my load temp in the ABIT EQ is 38º....

can someone help me with the raid 0 configuration?!?

[Entsafter]

it's really strange but with this damn board i've to high pcmark04 scores...
multi 14, fsb 299:
8427 POINTS!!!!
http://service.futuremark.com/compare?pcm04=2908616
can someone test with fsb around 300 mhz?

[maneshu]

wich cpu is yours?

[Entsafter]

3.8 E0

which motherboard do u have mate? if i set my fsb @ 275 with 14x multi on my asus p5ad2-e she wnt boot, as there is a bios bug when overclockin the board thinks im usin the 16x multi, only when windows loads will it stay with the 14x multi :(

I told you...even though the bios during boot keeps saying you are with 16x multi, if you selected Minimum Speed in Intel SpeedStep Technology you will e with 14x multi outside windows...so don't worry with that. :)

yes i kno u told me mate, but the bios still thinks it is a 16x so my board wnt boot with high fsb, there is no point me runnin 14x if i cant whack my fsb up, ideally i would like 300x14 = 4.2 but unless asus brings out a bios 2 sort out the bug then its a no go :(

highest i can do is 275 and my bios thinks its at 4.4 so i really need 2 up my voltage for it 2 even post
