Hello everyone, I'm having a very annoying problem and I'm not sure if it's the RAM or mobo.. Whenever I play a 3d game, my computer will freeze or just reboot within 10-15 minutes. I PM'ed MrBungle a few days ago because I couldn't post in the forums and he suggested to either underclock the fsb a little or up the voltages on the fsb and nb. Unfortunately, those suggestions did not work. I didn't want to underclock the fsb.. It's a small oc.... HardOCP couldn't really help and the OCZ techs in the forums helped stabilize gaming to ~40 minutes to maybe an hour before it freezes and reboots again... So I'm asking here hoping someone will be my PC GOD and help me figure out what's going on here. I'm not sure if something is going bad or what. Plz help

I recently upgraded my video cards from duel radeon 3870's to duel radoen 4870's. On my 3870's, I overclocked my E8500 cpu to 3.8GHz and 9.5 multiplier. That gives me a 400fsb running at 1600mhz. This is my first real experience OCing and it took me awhile, but I got it 100% stable. Prime95 ran for ~20 hours before I stopped it. Never had problems gaming. My mobo is the DX48BT2 with 1814 BIOS, ram is 2x2gb OCZ DDR3-1600 and they're in the black slots running duel channeled, psu is an Enermax Galaxy 1000w.

Last night, I ran Prime95 blend test for 13 hours, 14 minutes and got NO errors. I opened a game, and my pc reboot within 10 minutes...

Current timings:

vcore: 1.325v
fsb: 1.25v
mch: 1.35v
7-6-6-24 @ 1.9v are my RAM's factory settings @ 1600mhz. I've tried 7-7-7-24, 8-7-7-24, 8-8-8-24, etc. and nothing seems to keep it stable while gaming... 8-7-7-24 keeps it stable much longer though but it'll still end up freezing/rebooting. I've tried downclocking my RAM to 1333mhz @ 1.86v which I THOUGHT was stable but playing a game for about an hour froze my pc...

I'm not sure if this is even a mobo/ram issue... It almost seems like and heating/power issue but my pc runs fine when everything is @ stock settings... Thing is, stock clocks my RAM at like 1111mhz with 1.54v which is ridiculous but it works. Prime95 is stable but PC gaming is not. Could my Enermax 1000w psu not be supplying enough power to the cards? Or maybe my card(s) are overheating but I am using the fan mod.

[xMrBunglex]

i still think your vFSB and vMCH are low. if not, you might start looking at your video cards and video driver. the games you're testing on are important to know, too. but i'd up the vFSB and vMCH to 1.35 and 1.425 respectively first.

[DualCpuUser]

What proc are we dealing with here? I not catch that if mentioned.

I overclock the CPU (multi) to 3.6 GHz at stock 400 FSB and I run 1600 on my ram at which are dual ranked (double sided) sticks so I can push to 1600 with the vMCH not all that high.

I have 1 ATI 4870

My numbers are:
FSB: 400
Mult: 9
Vcore: 1.3270 (lower than the bios 'auto')
Vfsb(Vtt): 1.275
Vmch: 1.250
GTL: defaults
400/1600 7-7-7-18-60-6-5-8-6-1T
Vdimm: 1.90

i think that it could be your Crossfire configuration because your Cpu OC seems to be Ok, try with one 4870 only, do you have oced one 4870? what temps do yours 4870s have? after that try runing 3dmark and post the results to us

jumping to another topic, does any one knows what does "max cpu value limit" option in bios do?

[redrum5584]

I don't think it's crossfire because I have the same issue with just one of them as well. I did not have this problem with my two 3870's which I'm thinking about putting back in but man what a drag...

It could be a heat issue.. I'm thinking about buying a small fan and ghetto installing it by the graphics to help the airflow. There's very little room between the first card and the second card and the first card is 10c hotter on idle and load because of it.

I was playing Crysis Warhead earlier for 15 minutes and I quit because I figured it would freeze soon anyways and to also check the temp and my gpu and it was 90c. I have it set to have my fan speed at 100% when it gets 90c and above. And the fan control does work, my pc gets much louder when I'm gaming because of it. Windows seems fine. I haven't noticed any freezing or rebooting (YET anyways). Seems to only happen when gaming.

I just installed and ran 3dmark06 and I think I'm getting lower scores then I should be too. First time I ran the test, my computer reboot on Graphics Test #2... My fsb was @ 1.35v and mch was @ 1.425v. I dropped my fsb down to 1.275v and rose mch to 1.45v and ran the test again. It completed but I got a score of 18843, everything at default settings.

And DualCpuUser... What vcards do you have? When I had my radeon 3870's, my pc was stable with fsb @ 1.25v and mch @ 1.35v.

[Avantlord]

did you connect all 4 power conectors to both vgas?

[redrum5584]

did you connect all 4 power conectors to both vgas?

Yes, of course.

*edit*
Raising fsb to 1.35v and mch to 1.4v, 1.425v and 1.45v did not work. I'm beginning to think I'm screwed here.. I used to love this mobo but now I'm beginning to despise it... But who knows if it's even the problem. Seems like it is. All I did is upgrade video cards.

What's odd is I was using ATI's display drivers (v8.9) and the latest beta of ATI Tray Tools which is like 1.5.9.1314 or so... I removed them and installed Catalyst 8.9 drivers and Crysis Warhead will reboot my computer every time when I push space or esc at the Crytek logo. ATI Tray Tools didn't do that. I disable CrossfireX and I can pass the intro and start playing. My PC reboots mid game both ways though so I still have a problem.

*edit #2*
Well I gave up and decided to put my 3870's back in... Everything runs fine again... IDK what's causing the 4870's to run so crappy when system is OC'ed... Maybe it's a power issue but this psu is supposed to be good. Maybe it's a driver issue... Maybe it's just the cards. Anyone have an idea? Anyways, I'm probably gonna rma both of them and maybe try for one 4870x2.

[clark_carty]

Yes, of course.

Read my postings here, and on HardForum from weeks ago. When I went from an 8800GTX to a 4870X2, the memory no longer worked at 1600MHz. Dropping down to 1333MHz solved my problem. I was however able to go from 9,9,9,24 at 1600 to 6,6,6,12 at 1333, so I probably didn't loose much if any memory bandwidth.

[DoomBuggy]

Hi all,

Another newbee question here. I finally got my system together and booted up and moving through the bios one thing I noticed is that my CPU is only showing a 6mb cache, whereas I thought my chip had a 12 mb cache. I am just trying to make sure this system is set up properly before I begin attempting to OC it. This is my first try at this . System containes DX38BT mobo, Q9550 cpu (liquid cooled) , 8800GT video (liquid cooled) , 8 gb Kingston 1333 ram ( only 1 gb installed at this time ), and lots of hard drives. O/S is Vista x64 Ultimate if that makes a difference.

Thanks in advance for any help or direction you can lend,
Harry

[redrum5584]

^ Where'd you look where it said how much cache you had? Do you have the latest BIOS?

Anyways, I tried what you suggested clark and downclocked my RAM to 1333mhz and 6-6-6-12 timings and so far so good.. I've tried this before but with 7-6-6-24 timings. My system was pretty stable but then one time my computer reboot. I didn't try much testing at 1333mhz though. I think that's horrible to have to downclock memory because this board can't handle 1600mhz ram when you have a powerful video card... I see this motherboard differently now. I'm probably staying away from Intel from now on. Shouldn't have to downclock on something when you upgrade a video card. Hopefully it's something that can be fixed in a BIOS update but I doubt it. Intel probably won't release another BIOS for this mobo.

I haven't noticed any freezing or rebooting (YET anyways). Seems to only happen when gaming.

90 to 100C is not unusual for these cards. I doubt they automatically go to 100% fan speed @ 100C. I had mine @ 50% and they were way to loud. I would try bumping the CPU voltage in tiny increments and see if you get any improvement, being that your MCH is already up there. What is your memory voltage at ?

Also, try going back to 8.6 drivers and see what happens. Every new Cat after that has had some strange issue with this board or some detrimental effect on gaming. I think the 8.6 are the first ones to support this card, but don't quote me.

[redrum5584]

I had it set to go to 100% when it got to 90c and above with ATI Tray Tools. I stopped using ATT for a little though. Even with CCC fan mod, I have a hotkey to have 1st card at 95% fan and 70% on 2nd. I don't have stock coolers on my video cards so 100% fan speed isn't that loud here. I also have headphones so I can't hear them. The 2nd video card is 15c cooler then the first one because it has more space.

I have tried everything man. I've tried upping my cpu voltage up to 1.35v with no luck. I shouldn't have to put a ton of extra voltage into my cpu because of a video card upgrade... Right?

My stock RAM settings are 7-6-6-24 @ 1.9v @ 1600mhz. I've tried 1.9v, 1.94v, 1.86v, 1.82v, 7-7-7-20, 7-7-7-24, 8-7-7-24, 8-7-7-26, 8-8-8-24, no luck. Some of them made it more stable but every testing eventually froze my pc in any 3d game.

I have NOT tried any other drivers besides the 8.9's though. Maybe I'll try the 8.6's but I have little hope. I've been trying to get it stable for about a week now.

To summarize also, I could pass memtest86+ and prime95 at 1600MHz just fine. But when entering games, BAM, reboot. Only clocking down to 1333MHz solved the problem. There's something funny going on between this board, 1600MHz DDR3 (I have Corsair 2 x 2GB), and 4870X2s. I also have a QX9770, so my 1600MHz FSB was not overclocked.

I'm glad to hear you had a problem just like mine. Installing the 8.6's didn't help any. In fact, Windows keeps telling me that there is no ATI card detected when I install those drivers. Tried it twice. I even used Driver Cleaner Pro in safe mode to remove them.

I think there's something wrong with this board at the 4800 cards in general.

My computer froze about 30 minutes into Crysis Warhead when ram was at 1333mhz though.... Maybe I don't have the right timings/voltages figured yet but this sucks.

your cache is fine, is 6mb X 2 = 12mb, 6mb for each die

nice setup with WC you shouldn´t have problems

it can be a stupid question from my side but, do you have connected the molex conector in the motherboard? what temps do you have in your NB? maybe the NB just colapse when use 2 pcie with that bandwith.... some expert with an idea? i´m worry about this.....

[redrum5584]

Is there a program where I can monitor my NB temps? I've never seen the BIOS temp go above 50c. But I can't monitor that when gaming. I don't see how it would just collapse when I'm using the same voltage (1.35v) as my previous cards. Everest says my mobo temp is 38c right now. Clark had the same problem. His 4870x2 is basically 2 4870's... Maybe you should get another 4870 Avantlord and see if it happens to you? :p

Oh yea, I have nothing in that molex connector thing on the motherboard... The sticker says its a 1x4 power? Should I plug a molex from my psu into that?

*edit*

Connecting power to that molex on the mobo didn't help it at all. What is that even for? All that the instructions say about it is a diagram saying it should be connected. It must not be very important.

Well,
it may have been the 8.7's then, give them a try. I know I had the same issue, and reverting to the prior drivers helped.

I totally agree with your statement on this board and 4870's. There is something definitely wrong, but issues have always plagued Crossfire.

[redrum5584]

Yeah, it's stable when RAM is 1333mhz.. 400/1333. 6-6-6-12-60 @ 1.9v. 1.25v fsb, 1.35v mch, 1.325v vcore. Thanks clark for making it so.
I'll try the 8.7's perhaps. I e-mailed Intel about this issue though. Don't know if they'll do anything about it or will be able to do anything about it.

[DualCpuUser]

Connecting power to that molex on the mobo didn't help it at all. What is that even for? All that the instructions say about it is a diagram saying it should be connected. It must not be very important.

The extra power connectors are for balancing the power equally across the board, esp. when you have high power requirements pulling power from the PCI bus up to its design max.

It also keeps the chips in that whole area with proper votage and enough current.

Hey again Intel fans,

I'm just scratching my head in disbelief here.

I decided to go with the OCZ Extreme for Intel boards mem. (Reaper was too expensive)

1333 XMP.

I install the mem set it to profile 1. I leave all cpu settings and voltages stock in CPU. I'm showing 1333mhz on CPU and the 1333mhz on mem.

The thing won't boot!!!! Only boots at stock settings that show 1066 6-6-6-20
Shouldn't this thing boot?
Does anyone have setting suggestions?

Thanks guys.

is your CPU overclocked? i know that using the XMP profiles with an overclocked CPU will overclock the memory as well. if not, try raising the memory's voltage by a notch and see what happens. i'm not a big fan of memory profiles anyway.

[DualCpuUser]

Make damn sure you are on 1814 of the MB Bios. the previous ones outright suck.

1) "load optimized defaults" system should run. (reboot)
2) "Turn off things you not use, the simple things"
3) "Turn on HPET" (Windows likes this a lot!!!)
4) "Do not turn on EFI, my op. still broken with USB keyboards)
5) If things work, then turn on XMP profile 1 and reboot.
5.1) make sure the voltage if needed shows as updated, if not then flip to manual mode and all the parms stay the way of profile, but then bump up the volts to what is required for ram.
5.2) if not work, see #6


6) "BUY G.SKILL PC3-1600 7-7-7-18 2X2GB" I run just perfectly at 400(1600) at those timmings and even a tad less than profile #1

Hey MrBunglex, Thanks for the reply. I'm not a big fan of profiles either, but the fact is that this should run @ stock profile and yes, my CPU is stock settings, that's what's bugging me because this is Extreme OCZ mem for Intel extreme boards. I just wanted to see if it would run stock settings @ profile 1. You can't change voltage on XMP settings. It runs at 1.90v


So I contacted OCZ and said ''Hey dude what gives with the mem that won't run Profile 1 with stock CPU settings?''


Here's what I got back from them.

Please use these setting:

1333mhz
cas - 8
trcd - 8
trp - 8
tras - 28
command rate - 2t
trc - 36
trfc - 80

Memory voltage up to 1.75 Volts
Voltage of 1.66 or 1.67 seems to work magic on this board when nothing else will work.

Once you get this stable at these timings, you can go in and lower the timings 1 at a time and test for stability.

8-8-7-28
8-7-7-28
7-7-7-28
7-7-7-24
7-7-7-20

He says that there seems to be an issue with XMP and default settings with TRFC being way too low.

I also have a weird issue now in bios, My F10 command doesn't work. I have to save settings by the exit tab.

Suggestions are welcomed.

Thanks,
