ASRock 775Dual-VSTA overclocking experiences?

[Mr Vain]

Just overclocked my Pentium D 805 on the Asrock 775Dual-VSTA motherboard again from 3700Mhz to 3880MHz with Shamino's second CPU pin volt mod OF 1.5 VOLTS.

I did the first 1.420 Volt mod and the voltage in the CPU-Z is gone from 1.216-1.232 stock voltage to 1.36-1.376 and has allowed me to overclock my D 805 from 3400Mhz to 3700Mhz.

With the second CPU pin volt mod of 1.5Volts my D 805 has gone from 3700Mhz to 3880Mhz and the system is about 98% stable. I have posted at 4000MHz but might need more juice (Voltage) to keep it there stable. CPU-Z voltage has gone from 1.36-137 to 1.424 1.44 after the pin volt mod.

Memory has gone from 3-3-3-9 @ 3400Mhz with a 5/6 divider at to a 1/1 divider automatically @ 3700Mhz and onwards on my Geil DDR2 ram at 2T.

Temperatures are 24 ambient 44 at idle to 57 under heavy going with water-cooling. The VRM?s are needing good airflow with the extra voltage being produced otherwise everything seems ok.

Hi All!

I'm planning to buy Asrock 775Dual-VSTA and I have also checked other options for mainboard, so i stumpled on this:

Could Asrock 775Dual-VSTA's 300 mhz fsb barrier problem be similar to Conroe945-DVI: (quating Here)

This goes out to all the ppl having a ASRock Conroe945-DVI and are stuck at 299 Mhz:

Just put your FSB/PCIe to async AND put your PCIe-Frequency manually to 117 MHzs (or 112) and set your RAM-Settings manually.
Set your memory options manually, or use the memory ratio divider. I've set the ratio to 200mhz, which makes it work at 533mhz while FSB is at 350 (1400mhz). It's always best to run your memory at 533mhz with lowest possible timings (CL).

- sorry about my bad english -

 

[aussieburger]

Well I tried this and so far looks good ... currently at 315 bus speed ... I set the PCIe frequency to 112. Memory ratio has remained the same 3:4. Will do a prime run soon to see how it goes ... but 3DMark06 (1871 cpu score!), FEAR combat, and BF2142 beta run fine.

But I had never had this 300mhz limit that some seem to have ...

 

[xcelr8]

Changing the pcie-freq didn't do anything for me, still couldn't run 315fsb, it actually didn't just fail prime, it forced a reboot on the system.

has anybody tried the new bios and gotten a better o/c than with 1.70?

 

[xcelr8]

Does anybody reading this run a pci-e card on this board? I just bought a 7600gt from newegg and even trying 295fsb, which i was stable at with my agp 6600gt, it locks up after loading windows and i have to do a hard reset. It's as if it's not locking the pci-e freq even though i'm running it async in the bios and it should. Am i missing another option? Is there a program that can check the pci-e freq in winxp so i can make sure?

HWiNFO32 can read the correct memory speed of this chipset.


Here is a great program that benchmarks and also picks up your Memory Speed correctly.

FWIW I have my asrock motherboard stable with e6300 (stock), OCZ pc6400 platinum ddr2800 (@667MHz) with a cheap agp video card

 

[xcelr8]

I raised my pci-e to 117mhz and now seem to be running stable at 305fsb with the 7600gt. It seems that while it can lock the agp frequency it must use some weird multipllier and underclock the pci-e bus when you overclock the cpu, or maybe now. Either way, it seems to be working now, but this oc on the chip only raised my 3dmark06 score 50pts.

315fsb stable here.

(cpu-z shows memory speed wrong. Other is correct)
I was able to run Pifast @320fbs (4:29), but it wasnt stable. Using bios 1.80.

Nice board! :beer:

Now I'm gonna have to try the new 1.8 bios and see if I can get past 290fsb.

 

[Conky]

Well, I installed the 1.8 bios and set it to 300fsb (async PCI setting) and it failed to get into Windows. Then for the heck of it, I set the "Spread Spectrum" setting to "disabled" and it booted right up at 300fsb. It also ran Orthos fine for 15 minutes and survived several other benchmark programs. Topped out at around 48C.

I don't know if the bios made any difference because I was able to boot into Windows at 300fsb with the 1.7 but it wouldn't run Orthos for more than 3 minutes but I never tried to disable the spread spectrum before either.

I think setting the "Spread Spectrum" thing to disabled has been the biggest help to me so far so you might want to give it a shot if you are struggling to get a few more FSB out of this board.

 

[aussieburger]

hey nice tip Beachboy ... doing a quick bit of research it seems this Spread Spectrum should be disabled if you want to overclock:

I've been checking out various message boards and experimenting with this mobo again and have my E6400 stable at 2400MHz or the same speed as an E6600 which was my goal.

In addition to the above settings, I made these adjustments:
DRAM Voltage - High
AGP Voltage -High
PCI delay transaction - Enabled
IDE Drive Strength - Normal
Advanced Host Conf Pipeline DRQCTL - Enabled

I also have the onboard sound turned off(have a SBLive soundcard) and floppy disabled(cord wouldn't reach floppy, heh) in the bios.

I was able to run the Super Pi 32M in 23m 37.828s and also run Orthos for well over a half an hour before I decided enough was enough and turned Orthos off(I do have to use my computer too, lol). CPU maxed out at 50C/122F during this test with a factory heatsink/fan.

I feel comfortable enough with this overclock to leave it as my default settings. I'm sure I could go higher but 2400MHz stable was my goal and I have other factors limiting my overclock like 4HD's, 2DVD's, older power supply, etc. Hopefully somebody else can profit from this info. :beer:

 

[Mr Vain]

I?m Happy to hear that you achieved your objectives.

[Shibby222]

whoops sorry about that, anyway i have this mobo, and the E6400, and im looking to overclock it to the speed of the E6600, like the guy above, im pretty new to overclocking so i need some help

my system configuration is as follows
ASRock 775Dual-VSTA Mobo
E6400 Intel Core 2 Duo Processor
1GB PNY Gamer DDR2RAM
3HDDs, 1DVD Burner, Right now im using a GeForce 3...lol waiting on my GeForce 7 to come in the mail
520Watt PSU

Im using the stock Fan for the CPU, and i have 5 fans in the case, so hopefully thats enough to keep it cool for this (what seems like to me) minor overclock

if you need any more info about my system just ask and ill tell thanks for the help

 

[Shibby222]

hmm im using pretty much the same settings as you guys here, but i cant really get past the 2.25GHz mark, is it possible my peice of crap video card is holding it back?

Hey, You There! what is that desktop proggie you got running in the background with things like hard drive pace and cpu usage?

 

[awdrifter]

Anyone knows a vcore mod for this board? I'm using a P-D 945 and I tried VR-Zone's pin mod, seems like it doesn't work for 9xx series CPU, cuz there are 2 other people that posted the exact same problem I have. After the mod, only one core is functional, the other core is missing. I would like to keep the cpu and mobo, so is there a vcore mod for this board? I don't mind soldering at all. Thanks in advance.

I think that's Coolmon 2

I recently moved from an AGP card to PCI-E and my overclocking ability is way down. I was able to run at 300FSB with the AGP card with the settings I posted earlier in this thread.

I don't know if it's because of the changed power draw or using the PCI-E instead of the AGP but I am back to running at stock. And I have to set that manually too because if I set everything to default then the system sets the FSB to 256 instead of the stock 266. :roll:

All I know is I am ready to move beyond this board once I score some DDR2 RAM. It's a great board for people who want to re-use their old parts and upgrade piece by piece or for people who don't want to overclock at all.

 

[IEC]

Meh, my problem is a new mobo, E6400, DDR2 would easily cost me $400+

Whereas throwing in another GB of DDR and an X2 into my s939 rig would cost me <$200 and yield me only slightly less performance.

What FSB did you reach? What did you set for your PCIe frequency? Also, are you running with an AGP card or a PCIe card?
