can not wait!

My CAB2E 0540 FPMW just arrived. Results shortly...

Looking forward to it!

[Nem]

That a FPAW, FPBW or FPMW, Nick?

0540 FPAW

But is it stable @3.1?...I mean prime, etc...

Regards,
Primoz

Not had time to fully test yet, it's doing 1M super pi so far. So got get back to work now tho, only came home to check the stepping Then ended up installing it to test.

ok guys, have my 146 cab2e today, and have a slight problem

during bootup the cpu detects as 146 operton, but runs at 200x9 - 1800mhz

im using hellfires latest bios. (in bios the maximum multiplier i can select is 9)

any ideas?

Sounds like someone is telling porkies to me? The only cab2e chips available so far we've seen are the 144's, all current 146's are coming cabye. And if it's booting with a 9x multiplier then it would seem it's a 144. You checked on the chip itself, or have a pic before you installed it?

sorry im loosing it. its a CABYE 0540FPBW

[Nem]

Hehe!

What you got set for the cpu multiplier then in the bios?

Nick

[Azh_fx]

i saw that edit "cup" lol

If the highest multiplier in bios is a 9, you got a 144. Did it say 146 on IHS? Try the DFI 623 bios.

[Azh_fx]

yes it does :S

[ChRiiLLe]

Where do you buy your CAB2E processors? Is it only CPUCITY who has em' ?

[Brocon]

nope, they are from cpu city. Mine is on the way.

I have to say i'm wishing that I had a 146 CABYE looking at the results others are getting with them..
Just crossing my fingers that the CAB2E is as good or nearly. Knowing my luck it will be poor tho.

[Cossey]

cab2es are at cpucity

plz

I can not wait!

Any UK guys got a 146 from Scan yet? Sorry if it's already been posted, cba to read through 88 pages :p

Suman

[Richdog]

Interesting... a guy on OCUK received his 146 and it also defaults to a 9x multi (1800mhz) and will not let him select 10x...

[Sumanji]

Yeah I saw that, he still got a sweet overclock though probably just a BIOS issue?

Straight in at 300x9 1.35v was perfectly stable, I'm currently trying to work through some issues with my Neo2 not handling the high HTTs before I go much higher than that. Had a POST at 333x9 (3GHz w00t!) but it crashed at DMI. This is all with a TDX running off a single BIX, Neo2 and GSkill LE.

I also appear to have lost my 1T/2T setting in BIOS, I'm on 1.37b so it should be unhidden but it isn't...just gonna go try the shift-F2 alt-F3 wizardry (it'd been so long I forgot how) and see if it's disappeared off to there, but TBH I'm a bit confused on that one. Where'd it go?

[Jimbo Mahoney]

not handling the high HTTs before I go much higher than that. Had a POST at 333x9 (3GHz w00t!) but it crashed at DMI.

Is that immediately before Windows loads? You're running XP SP2 right?

In which case, TRY this:

Change the following in boot.ini

/noexecute=optin

to this

/execute

That will turn off DEP, which caused all sorts of problems with high HTT on my Venice 3000 and DFI Ultra D. For some people, it lifts a magic brick wall, for others it does nothing. Worth a try...

[Brocon]

Jimbo, can I quickly ask what DEP is?

[Jimbo Mahoney]

Jimbo, can I quickly ask what DEP is?

Dynamic Execution Prevention. It's some sort of additional virus-protection in the OS.

Is part of SP2, but can be turned off. It cannot be disabled in Windows x64.

I think it was a guy called Sharp from DFI forums that pinpointed it after I tried 2k, XP, XP SP1, XP SP2 and XP SP2 safe mode.

XP SP2 was the ONLY one where I couldn't get over 2.5 Ghz. In all the others, I could boot into Windows @ 2.9 Ghz. It would just lock before loading Windows when DEP was enabled.

Weird.

[Sumanji]

Jimbo can you not just turn off DEP from the System Properties window or does that not have the same effect?

Cheers,

Suman

[Kameleon]

Is that immediately before Windows loads? You're running XP SP2 right?

No, it's immediately before UBCD loads, and I'm running Win2k. Good info though, one to watch out for

More info on the 1T/2T thing...it's actually just ing vanished. 1.37b does indeed have the "secret" options enabled as default, so hitting the combo just turns off half the options. Grr. Anyone got any ideas?

[Jimbo Mahoney]

Jimbo can you not just turn off DEP from the System Properties window or does that not have the same effect?

Cheers,

Suman

Not the same.

You'll also notice if you do the boot.ini switch, the DEP stuff is TOTALLY greyed out in Windows.

If it has no effect, you can always change the switch back again, it's not a reinstall or anything. I leave it off all the time on my gaming rig now. It's just another variable for me I'd rather eliminate straight off the bat.
