ASRock 939Dual-SATA2 VCore & VDIMM Mod

ok, have you check the cables to see if they aren't switched? I have never heard of such problem... Not even with other mobos... But I don't think it will much of a problem if all is working fine... maybe it's a glitch...

yeah I checked every thing and it is just the case power light that stays on after a shudown . I can't see it as hurting any thing as it is just a light . and it all works better than ever too.

see, there's no problem... today I was gonna make the variable voltage mod, but there they didn't have 500 Ohm trimmers and 2.1K resistors... Guess it have to wait, tomorrow i'm gonna search in an arcade repairing shop to see if they could "lend" me some... eheheh

 

[c3l5o]

looks like it worked, ill put some pics later on... I couldn't find a 2.1K Ohm resitor though... I mounted a 2.2K one and then fined tuned a variable 0-1000 Ohm resistor instead of the 0-500 ohm suggested and now I have a rock solid 2.85V Vdimm... I'm very happy and my TCCD are too

Best regards

thank you in advanced for those pics. I hope solder points aren't so small like i think and i can do it with my soldering skills.

 

[c3l5o]

sory but I can't take pics of it... the isolation in the wire that I used is too thick and I can't take the pic...

HELP! Im an overclock newbie...
My problem is that I cant even get started with this board due to my cpu frequency settings appearing to be locked... I can enable the cpu/pci-x frequencies but when I press enter to change them... the frequencies fail to appear?!
I've been on bios 1.1, 1.2, 1.4 & 1.5 with no success.
Ive had this problem b4 with a laser locked 3.0 barton, & obviously it was locked. Im hoping my 3200+ venice e3 isnt the same?
Does anyone know if I could have a 'venice' that is locked up?, cos I cant think of what is causing this... (
Any advice would b much appreciated S
cpu-z says my venice is a revision dh-e3?

I only want to o/c to around 2.3 to 2.4ish, and dont want to v-mod

 

[c3l5o]

I've got a 3.2+ venice myself... CPU-Z DH-E6

I think you can't even get near that without making the vcore mod on this board...
Sory but I just can't help ya... mine is at 2.3Ghz and I only get it stable arround 1.5V...
My old 3.0+ was a mad overclocker, 2.8Ghz stable at 1.550V, It was a bad change...

...was that one a winchester?

...was that one a winchester?

Both venice...

finally I have been decided to make variable voltage mod but i didn't find a 500ohm resistor so i bought 470ohm. Will i reach the same 2.85v (normal)- 2.95v (high) with this resistor?

Found how to o/c on Asrock dual sata2 doh S

...dont laff cos i havent seen that one before.

In case anyone else hasnt seen it...
to change the cpu frequency in dual sata2 bios, you must

-set overclock mode to: cpu/pci-x asynchronous
-move to the newly enable cpu value and hit delete to delete the value
-insert the value u want & save

...every other value in this bios and every other motherboard bios I have seen in gives u a menu to do this & it wasnt immediately obvious

...thought someone would have said something! lol

Anyway, got my 3200+ venice up to (240*10@1.45v) 2.4G on a 5/6 (333)mem divider giving ddr400
50oC on full load after hours of gaming (is this high temp?) barton used to run at 65 not o/c
As well as my 7800gt up to 450 core 1200 mem! hooah! 58oC full load after hours of gaming

Im satisfied with that...
3800+ & gtx speeds for £300 & rock solid
...maybe time for some zalman cooling tho S

can anyone post pic with a further zoom on where the Vcore mod area is located

 

[W1zzard]

can anyone post pic with a further zoom on where the Vcore mod area is located

it's right next to the cpu

 

[EarlZ]

on the first page of the post it says "With an AMD Venice CPU the maximum CPU voltage available is 1.450V, definitely not enough for some serious overclocking."

so if i use a Sandiego core ? do i still need a voltage mod ?

 

[EarlZ]

it's right next to the cpu

just based on the pic posted, noticed it was placed under the CPU bracket.. still dont have my mobo tho.. will arrive this afternoon i hope

 

[W1zzard]

not sure about the limits with san diego .. i know that it is higher for athlon fx cpus. let us know your findings

Can someone help me out with my 4800+? I can't get it to o/c hardly at all. I'm not even getting into the FSB ranges where I need to mess with the voltages yet.

I'm only trying to go from stock 2.4Ghz to 2.7Ghz based on a few articles I've read. They were setting the memory to run at 333Mhz, setting the HTT to 3x and running a FSB of 225. I can't even get XP to boot with FSB of 210-215

I'm using BIOS revision 1.5 and I have the memory voltage on high(2.7v) and have tried Auto on Vcore voltage as well as 1.4v. I have 2x512MB OCZ PC3700 Dual Channel Gold Edition with default timings of 2.5-3-3-8. In case it matters I have a 6800 Ultra 256MB AGP video card.

Anybody have any advice? My memory is rated for 466Mhz but it seems to be having problems with 420Mhz I guess I'm suspecting the memory but OCZ Gold is supposed to be one of the best o/c brands to use.

 

[EarlZ]

got my board after 1 week of wait, it was dead on arrival. no beep errors nothing...

edit:

was also wondering if the SP-120 would prefectly fit on the Asrock S939 Dual Sata2

 

[EarlZ]

what does flexebility option actually do ?

Solder point R642

Hey

Thanx for a great site! with a lot of great info!

Did the vcore mod, but as I ran out of luck doing it, I burned the solder point R642 left badly. (the first one up to the left from where you connect the two solder points, while doing the mod)

Any who knows what it controlls, and how I could check if its damaged or not???

THANX!!!!!!!!!!!!!!!!!!!!!!!!!!

 

[W1zzard]

r642 is just an empty pad as it seems shouldnt affect operation as long as the two pads are not connected by solder

 

[Dre78]

Thanx
Amazing what stuff you guys knows!

This forum rocks!!

I'll have this site bookmarked and will highly recommend it!

again thanx alot for the quick reply! I'll get back to tweaking my system! happy to know that it should be alright!!

 

[c3l5o]

You've got luck... Mine is now fried... couldyou post some pics?

 

[Wam7]

For those people running 2-2-2-5 timing on this board, I think you will find that 2-2-2-10 will give better memory bandwith and higher scores.
