Yay I can edit the size of my memory! I've been wanting to upgrade to 2 Gigs.

umm please don't do that .. you will just end up with unusable memory

POGE · Nov 17, 2006

It was a joke.

DaMulta · Nov 17, 2006

Is this for memory in your system, or memory on the video card?

thx wizzard,now i know why my machine wont boot if i try cas6.in the output from this it says-
cas supported 3,4,5,i guess thats why eh?.it means i cant try cas6 tho' for higher mem clocks am i right?.

thx.interesting,but i dare'nt change anything.

zekrahminator · Nov 17, 2006

It's not compatible with my budget Gigabyte board, I wonder why

.

Wow, nice program.

I saw them discussing 'flashing dimms' over in XS, but i didn't really follow, but this is just cool!

Thanks

Frogger · Nov 18, 2006

DaMulta · Nov 18, 2006

Wiz, the Nforce2 chipset is not supported.

Whoa.. wait.. I didn't realize this can edit SPD.

YEAH!!!!!!

You rock.

You need a cookie. Someone get this man a cookie!!!!!

Batou1986 · Nov 18, 2006

so this basically can be used to edit the settings on the ram so it defaults to certain speeds and timings ? this would rock if i still had that dell

p-jack · Nov 18, 2006

unfortunately, the program doesn´t seem to like my mobo... when i start it it says "no memory modules found. incompatible smbus driver?"... board is an asus a8n-e, nforce4ultra chipset...

Batou1986 · Nov 18, 2006

Works fine on my Gigabyte K8U-939
North Bridge: ULi/ALi M1689,
North Bridge: AMD Hammer IMC,
South Bridge: ULi/ALi M1567

also for you guys having trouble make sure u have any and all programs closed through task manager that address the sm bus such as hardware monitoring programs and such

W1zzard · Nov 18, 2006

first post updated with new version

regan1985 · Nov 18, 2006

looks like a ace program!!! there any guide yet?? im not sure what i can play with to get better performace and if u should go higher or lower?!!
cheers once again a great program :toast:

Crisao23 · Nov 18, 2006

Awesome utility !

Thanks !!!

Steevo · Nov 18, 2006

Should we start comparison charts with respective OC's @ timings and volts?

W1zzard · Nov 18, 2006

i will be adding an upload spd feature soon so that there will be an spd database like the bios collection .. people can add comments there and share their overclock reports

DaMulta · Nov 18, 2006

Thanks Wiz, just a question how dangerous is this program?

Steevo · Nov 18, 2006

As dangerous as any program. You just gotta know how to use it or be wlling to accept that you might damage hardware during learning.
