emm i tot mantaray bios have a boot up pic of "mantaray"??

erm...

gk wong, mind sharing with us how u changed the logo ?

Sometimes its just too fast until u cant see what's on the scree.

it can fit barton cpu. it stated there athlon and athlon mp/ xp series... i thought barton is also athlon xp?

What i meant was, the core size is different although its an Athlon XP.

I think its not that expensive either rite ? So its not a waste to test it. Who wanna be the guinea pig ?

i've installed the copper shim on my barton 2500+ cpu. And I can confirmed that it cannot fit smoothly on the CPU. Yes, the copper shim can inserted into the cpu but not perfectly matched.

And when I sandwiched the copper shim between CPU and my thermaltake volcano, the thermal was worsening because the copper shim distanced a bit the core from touching the base lap of the heatsink 

Previously without the copper shim, the load temp was about 52° C (primed for two hours). With the copper shim, the load temp was around 55° C (primed just for 10 minutes) 

I think I need to bring the copper shim to any specialist in metal cutting to modify the hole so that it can fit firmly into the barton CPU.

The Incompatability here is the 4 cushions hole size ?

Is it TRue ?

gsan back to NF7 oveclocking world 

got an identical 512mb corsair bh6, so now running 2x512MB bh6 with ocz ddr booster (vdroop mod).

previously used 1T bios, found that 2x512mb bh6 cannot overclock well with timing 2-2-2-11, even with any high vdimm.

flashed to d26-mantarays-xt 2T bios, able to prime 230 @ 2-2-2-11, 3.2v stable. and now priming 240 @ 2-2-2-11. 

yes, the bh6 is double sided. mantaray xt 1T gives no more than 210 even i pump it to 3.5v, so i switched to 2T and it can prime stable at 230 for more than 5 hours. but what made me disappointed is nf2 memory controller cannot handle double sided ram as well, prime 240 failed within 3 hours.

p/s: all tested at timing 2-2-2-11.

I think its the memory problem. From what i know, the Air Brand with TCCC chips are relabeled chips. Secondly, mixing ram with different configuration and types do affect the overclocking process.

Mosel Ram Chips

Vitelic 5ns - This is 5ns ram from Mosel. It is commonly found in PC3200 offerings, and at this speed is rated at cas2-3-3-6. This is not bad, but nothing out of the ordinary. It is similar to CH-5 from Winbond. This ram can clock to around 240 MHz and hold decent timings such as cas2.5-3-3-6. If timings are kept at 2-3-2-X, then this ram will typically max out around 220 MHz. This can be found in Corsair XMS3200, Geil Ultra PC3200 and PC3500, OCZ PC3200 and PC3700. This is not a bad choice of ram at all. It offers great overclockability while still holding very respectable timings. Although Mosel is not a well known name in the memory industry, you can see that the top memory manufacturers are using their ram. If you can get these on the used market, they would make a very sweet deal. I have not seen these in Value Ram offerings, but that does not mean they do not exist. Identifying these can be somewhat difficult, as many companies re-label them. Take a look at the ram list to be sure of what modules contain these chips. You can identify these chips by the last 5 characters being SAT5B.

i got 2x256 Corsair BH-5 PC3200 ,any1 interested?i can sell coz din play OC anymore.
can reach 8-2-2-2

haizz... missing my old nf7 board.

anyways,

i tried my Team Xtreem on the NF7, but couldnt get the timings 2-2-2-5

so i had to changed board and pumped the voltage to 3.3v and manage to get the timing.

gsan, the DDR booster u used can pump up to how many volts?
Thanks...

I might be getting NF7 mobo for my 2nd rig. Will see how far it will go compared to my fried NF7 mobo. Old mobo i can clock it around 255mhz for the ram using hynix d43 rams. Proc can go around 2.5ghz with 1.85v. But its weird since i cant use 250x10 at all.

errr... my bios dun hv tat selection... my bios is the latest ady...

tq

I also faced slightly similar problem aforementioned. Sometimes I will be "greeted" with the BIOS checksum error message upon POST stage. I wonder if the circuitry beneath the battery compartment was damaged so the battery can't deliver it's current to ensure the information kept in the BIOS chip intact. OR is the BIOS chip was flawed due to high activity of overclocking experiments?

If I change the BIOS chip with my spare BIOS chip, will the problem solved?

I welcome anyone to express the idea to solve problem of both of me and -=J4cKa5s=-.

to sarge hassan, gsan, mr_47, gkwong or zahri:

If anyone of you have, I am asking your favor to send the BIOS file of D26 Mantarays XT 2T. In .bin format.

Thank you.

I am busy with Cisco Academy Program class so bz now to surf every pages regarding to this topic, in order to search links to get the BIOS file.

EDIT: my email is amretz@gmail.com

@GKWong

Thank you for sharing the BIOS files. I should credit you for the nice POST screen that u custom made. I like it!

By the way, I am still finger crossing that after flashing my BIOS, I need not have to swap to my spare BIOS yet.

nah, BIOS still show BIOS checksum error - default loaded.

I have to change with the spare BIOS and see what will happen afterward.

I'm officially quit from NF7 world.

My experience with this mobo:

Pros:
1. Great overclocking potential.
2. Can moded. to 3.3vdimm/ L12 mod / Vdd and Vcore pencil mod. easily.
3. OCZ DDR Booster up to 4.0v without VTT track.

Cons:
1. Poor memory tweaking bios option compare to NF2 LP rev.B
2. Double sided BH5/BH6/UTT cannot overclock well with high tight timing @ any vdimm
3. No cooling on southbrigde cause instablity during high FSB overclocked.

yup, espeically during high fsb, the ps2 keyboard and mouse will stop function while the system still running. after giving cooling on it, no longer have this problem.
