ASRock 775i65G

[Magnus6]

Hello, i have the exact same problem with my ASRock 775i65G and my Raptor 150 gb, i upgraded to the latest bios 2.70 and it also see it in bios but when it comes to windows install it says it can't find it.. im currently running with my 60gb Seagate Barucada IV ATA drive, and in windows it doesnt even see my raptor either even though its still connected..

plz help me also! id like a beta version also

hello Magnus6, the patched bios will be ready in couple of days and it will be at Asrock's site, just bear with us for a little longer when we waited for all issue to be fixed or unfolded. thanks.

It would be nice with the new bios if the 300 fsb maximum be raised to 350, perhaps? I think these CPUs would go much higher, if the m/b can handle it without overheating or other issues?? Even at 300 fsb the system is as stable as an (As)Rock!

I hope everyone would understand the limitation is not the bios but the chipset itself, the original design of 865 chipset will only go up to 800FSB, running the c2d @ 1066 is already 33% oc of the chips, if go to 1200, we are talking about 50%, and @ 1400 we are talking about 66.7%, are you sure that's wise and worth the risk that's invloved?

 

[Magnus6]

i don't think the FSB should be raised.. due to the fact that the people that buy this board don't do it for the OC.. if you wanna do heavy OC you would use another chipset


i guess ill have to wait then kinda itchy to see it running!

yep, that's about what I figured. My rig running smoothly at 1200fsb is already a bit of a stretch @ 50% OC, so to ask for more may be dreaming...

Okay, I have been using the beta bios for the whole weekend now. Everything seems to be fine now that I have switched out the memory. I think those were just not a good batch of memory. I remember it not behaving smoothly in my previous comp. Gaming went fine, surfing, word processing, and everything went smoothly. I am now happy with this computer. That Rapter sure makes a different. For the price, this mobo let me keep my memory, and my (previously) expensive 6800 GT. Thank ASRock for working on the Raptor issue.

 

[Magnus6]

sounds very nice muzzy! hope this will be up soon then cause im kinda itchy to get my raptor going =)

Hello to all,

I've got the same problem as Muzzy and Magnus6 : WD Raptor 150gb not working with my Asrock 775i65g, bios 2.70

thx to you, Rkwork, I've red your reply about this beta bios, or a new one incoming; where can I find these?

If it take long time to distribute it, i'm ready to do beta bios too and send Asrock feedback.

a nice day to you all.

 

[Magnus6]

Hello again... i got this email this morning from Asrock support


Dear Sir,

Please try to disable "Spread Spectrum" in the BIOS.

Thanks for the email.

Yours truly,

ASRock


Im now speaking from my desktop running my raptor !! it works ))

To disable Spread Spectrum just go into advanced in the bios and under CPU there is an option called Spread Spectrum, disable it and save and exit and it should work.

Hi Magnus,
I've got an E6600 775i65g rig too. Works great until i try pluging in my 7800gs...then it won't post consistantly. I haven't tried the Spread Spectrum thing yet, maybe that will help. Your RAM is faster, so that might make the difference. Mine is only rated at 2.5-3-3-8.
I wonder if you are you running with the Flexibility option enabled or disabled?

 

[Magnus6]

Hi Hibachirat, the spread spectrum is for getting WD Raptor 150 GB hard drive to work..
i was running that latency untill today that i found out that i should put it to 2-3-3-6 instead..

 

[hibachirat]

Oh yeah, thanks, i probably shouldn't have posted in the hard drive thread here, but happened to see you were using 7800gs and at this point i'm willing to try anything. Asrock recommended an ultra clear CMOS (pull the batter and the power supply-to-mb connector).
The latency comment is interesting though. Are you saying you had better stability with lower latency settings?

 

[Xvys]

Trying to tighten the ram latency is the only thing that will crash my computer. If it reboots during heavy usage, I have backed off the latency settings, then all is fine and stable.

This m/b requires cas 2.5 ram to run at the default 1064FSB with the ram running at 178 mhz (266 x 2/3 divider). The "Auto" cas setting is 2.5 on my computer. Overclocked to 300FSB the ram is running at 200 mhz, which is pushing my Samsung ram a bit @ 2.5-3-3-7...Especially since one of my 512 ram sticks is rated only 3-3-3-8 @ 200mhz.

 

[hibachirat]

Hmmm, I don't get crash problems. Just POST problems. I think it's this AGP card. Finally tried it in another motherboard (AMD/VIA) and that one will never complete a POST with it installed. Otherwise that machine runs perfectly. Oh well.
As for the 775i65g, it's curious. I seem to get the same bus speed with or without an AGP card. It runs rock solid at 299.5FSB bus 1198MHZ with either my 2.5-3-3-8 or 3-3-3-8 rated RAM parts. Memory at 199.7. The manual indicates that the BUS should only allow 3x the FSB without an AGP card, but I'm not complaining.

 

[Marco775]

Thanks Magnus6!
The tip of "disable spread spectrum" under cpu in bios rocks! my raptor runs like a charm now.

 

[Magnus6]

glad to hear *cheer*

I have recently bought a AsRock 775i65G along with an E6300 and am trying to O/C. At DDR400 and 300FSB, I seem to be having some problem running Prime95 and playing games will lock up.

I am currently running my RAM at 2.5-4-4-8 and that is the slowest I can set the memory latency at on this mobo. Also, I have enabled the "Flexibility Option".

My computer does seem stable at 290FSB (memory at 193mhz), but I would really like to get up to 300FSB. Any suggestions?

As a note, I recently also bought a Fortron 400W PSU and have a BFG 6600GT video card in the rig as well.

Could someone who is successfully stable at 300FSB generously post their BOIS settings?

 

[Magnus6]

well i have had my E6600 run at 300 mhz without problems and at full load at 36 celsius.
DDR timings is 2-3-3-6 at 400 mhz (prime95 extreme test)

There is not too much to change in the bios, but I disabled Spread Spectrum; disabled the Ram Compatibility Mode; set both Voltage adjustments to "High"; hmmm, all I can remember right now...

The difference between 290 and 300FSB is not very much. My "Auto" Cas setting is 2.5, or I can manually select either 2.5 or 2. You would think Auto would be Cas 3, but it does say in the manual that in 1064 mode the required ram is Cas 2.5. This may be fine at 266FSB (2/3 divider = 178mhz ran speed), but if you overclock to 300FSB = 200mhz, perhaps this is pushing some ram too much, even at 2.5-4-4-8. I have one 512 stick of Samsung Cas 2.5 ram and one Cas 3 stick, running at 2.5-3-3-7, which is very little improvement over 4-4-8 in the benchmarks.

 

[hibachirat]

Mine is also stable at 300FSB.

I've achieved this with two different sets of SuperTalent RAM and at various memory timings.
With 2x512MB PC3200 rated at 2.5-3-3-8. operation is stable at 2.5-3-3-7 or any slower timings such as 2.5-4-4-8
With 1x1024MB PC3200 rated at 3-3-3-8, operation is stable at 2.5-3-3-8 or any slower timings such as 2.5-4-4-8
Flexibility option is disabled and RAM runs at 3:2 ratio = 200.
Spread spectrum is enabled in my system with both SATA primary and PATA secondary Hard drives.
No overvoltage (not that this MB allows much).

As of last night, i finally solved an agonizing problem with my 7800GS that i'd blamed on the video card and/or the motherboard. The real culprit turned out to be a new Enermax EG495P 485W PSU--the one part I would not have suspected until it failed completely after about the 30th install & removal of the big AGP card. The system is now running happily on a junky featherweight PSU that I pulled out of an abandoned Dell Dimension case. System wouldn't boot until i disconnected the 2nd hard drive and one case fan, but now runs fine. With the Enermax and the 7800GS, i only got this rig to boot to XP about 5 times in 10 days of endless testing and tweaking (with no overclocking of course). Today it's in XP for the 5th time with this junky PSU. More and more, i find that system problems keep coming back to the PSU, so don't hesitate to suspect that as your weak link.
