Hi guys,

I bought myself a new rig after 5 years of sticking with my old pc. At the end of the day I want STABILITY and no hassle. Yes, i want the thing to be fast, but fast at standard, stable settings.

Upon reading reviews, it seemed like the Asus range of x38 and x48 boards were the most stable, whether OCing or not. THerefore I went and bought the following:

Maximus Formula
4gb Crucial Ballistix 4-4-4-12 PC6400
BFG 8800 GTS 512 OC
WolfDale 8400
Corsair 620W PSU
Hitatchi 1TB HDD (forget the name, but its the 32mb cache one).

I am running windows XP SP 32bit with the PAE enabled (so have 3.5gb avail physical mem), bios revision 907, and latest drivers all round. All settings are default or auto, which means no o/cing at all. I dont use a 64bit OS as at 4gb of mem, the extra address space required by 64bit addressing basically wipes out the fact I can use the full 4gb.

The problem im having it is the system just feels a bit flaky when i first built it. It's hard to explain, but compared to my aging abit IC7-G + p4 3ghz, it just felt more unstable. For example, certain actions would be consistently, guaranteed slow on my old pc. On this pc, sometimes they would be like lightning, sometimes quick, then slow, then quick. Simple things like opening a large file, or FPS in games. A good example is World of Warcraft. Generally silky smooth, sometimes slightly jittery, even in the same area. Not a huge issue, granted, but i just splashed out on near top of the range kit, and i dont expect this randomness!

I thought I was just being pedantic and ignored it, but after a few days of using the pc on and off (not leaving it running 24/7 either), I got a few lockups and reboots. I decided to investigate further and found the NB soars to a whopping 53 deg C after playing games for a few hrs. Now this strikes me as ridiculous. I know for most of you guys its fun to just prise off the heatsink and fit water cooling or an active fan, but really, this is beyond a joke for me. I am a software engineer by profession and qualification, and I spend all week messing around with server clusters, threads, pointers etc. At the weekend I just want to relax with a stable system! Asus should not be selling a product that is defective out of the box and requires user modifications to make it work!

I generally leave all BIOS settings as default, not because I dont understand what they do, but because I want stability. However, i did try dropping the NB Voltage to 1.25v as the default appears to be 1.35v (rather high). This did make the temperate rise more slowly, but it seemed that once the GPU hit around 58 deg C, I would get serious artifacts in game and guaranteed lockups everytime. Therefore I changed it back to default and that issue has gone. It does strike me as odd though that the default NB voltage is so high (is this high?).

However, something tells me that it might not be the NB, but the gfx card itself, or a combination of the two. I notice "inconsistencies" in some games such as a texture being seen through a wall at a distance occasionaly. Again, i wouldnt call this an artifact, it's just an engine glitch (probably), but it makes me dubious as to whether it really is JUST the hot NB that is the problem.

I have tried tweaking things like the spread spectrum, and even lowering the GPU mem and core clocks beyond normal. This has made no noticeable difference - although the system hasnt crashed again yet, it still feels randomly flaky...sometimes smooth, sometimes skipping a few frames. THis means I am constantly on edge, just waiting for the thing to lockup again.

3DMark and SUperPI go through on multiple runs no problem, and it generally appears rock solid from a synthetic point of view.

Another problem is the sound. I am using the FX-II. It sometimes repeats for a split second when frames do drop. Also, when I plugged in my headphones to the green socket, it asked me what I plugged in, whereupon I selected "front headphones". It then told me this was the incorrect socket and showed me a diagram, telling me to plug it into the green socket...which is where they are plugged in! I got around this issue by telling the damn thing im using "rear headphones". This again isnt a big issue, but its just another problem I can't be bother with fixing.

The worst thing is, even other vendor's offerings use damn heatpipes too, so if I get an Abit mobo (my fav manufacturer generally), ill have the same temperate problems!

Too me it feels like too much is crammed onto this mobo for it to ever be stable: HD audio, 2x pci e slots, 6 sata slots, 2x lan slots, the crappy JMicron controller which i am also dubious about.....I wouldnt mind sticking a NB fan on if the mobo came with an optional one, but the fan it does come with is for a passive CPU cooler....There doesnt appear to be any decent way to mount a fan except to buy the Revoltec 50mm and some bolts, but im struggling to see where I can get these in the UK!

I guess what im asking is:

- Is this too hot a NB temp? (I cant find a whitepaper on the default voltages and temps, just mobo reviews which arent detailed enough)

- Are their known "bad batches" of the BFG GTS 8800 O/C or Maximus Formula

- Could it be a ram issue? Incompatibility or worse

- Any way I can establish whether it is the NB or the GPU? I have tried using a hairdryer (for a VERY short period of time) to increase the GPU temp to 70deg and then after I let that cool for an hour with the system off, I did the same to the NB. I was trying to establish if heat on either was the cause of the problem, but I (unfortunately?) noticed no discernable difference.

Sorry to vent in such a stream of consciouness way, but I just expected more from the system than high benchmark scores.

Any advice/help is greatly appreciated.

Thanks.

sp00d,

Unless I missed somthing you hadnt stated which version of the BIOS your running on the motherboard, might be worth making sure its the most recent or if someone with this motherboard could make a recommendation as to which BIOS is best suited to the E8400.

Sorry I dont have this motherboard but it would be my first point of call unless you've already done this.

Regards,

I ignored his temps as I dont know limit on his Chipset, its 90C on NForce's but even thats gonna act up, 53C if correct does seem fine :)

Assume he has read that from Bios to make sure its accurate.
 
Sorry for the late reply guys,been so busy with work that the mobo seemed the least of my problems! One thing I did try was to turn off the memory remap feature which I THOUGHT was required to enable > 2gb on 32bit XP. This hasn't really made a difference though as last night everything was fine...played bioshock for a few hours. Then I went to browse some images with Irfanview and the thing just locked up on me again with my MP3 just looping overand over in winamp. Temps were quite low (< 45 on both NB and SB), and < 50 on GPU.

I have crucial ballistix mem and its set to default timings which arent the claimed 12-12-12-15, but 15-15-15-18...does this mean that although the mem requires 2.2v to run properly, the default is actually not enough to make the mem stable at even relaxing timings? I will try upping the voltage tonight.

Thanks for the advice.
 
Not sure if your timings are correct for any ddr2 ram i have seen , 5-5-5-15 is a more usual setting for timings i think , can you check the default timings out as they dont appear right to me. Just looked at the spec in your first post, have you tried using the default values?
 
Crucial Ballistix DDR2 PC2-6400C4 800MHz CAS 4-4-4-12 Timings, 2.2v VDIMM. You might have to raise the Northbridge Voltage by +0.1v above the lowest setting to boost the board for running four sticks of memory.

Yeah, thats the strange thing....the default is definately higher than that. More like 5-5-5-18 or 5-5-5-15...I cant check now because im at work. But isn't it strange that the default settings arent what Crucial quote them as?

From what I've learnt mobos regularly don't get the exact timings on memory at default and you have to manually change them.

I personally don't find it strange.
 
Your board is basically the same as mine except yours has a couple more fan headers, LCD post code and a couple of other things. For your board running a E8400 you need the latest bios, version 907. Download it to a USB stick (it's too big for a floppy) and flash it on startup by pressing Alt+F2 and running EZ Flash.

DDR2 will hardly ever set to it's default timings and mostly set's itself to run at 1.8v. You need to go into the bios and under the AI Tweaker menu set the AI Overclock Tuner to Manual. You will then be able to set the Vdimm voltage to the 2.2v that your ram requires. You have to type the voltage in. While you are in there set the timings to 4-4-4-12 (Cas Latency/Ras to Cas delay/Ras Precharge/Ras Active time), leave all the other to auto. The Crucial Ballistix PC2-6400 is compatible with your board.

53 degrees for the NB is nothing to worry about. I had a 965P DS3P that would burn your finger if you touched it. The stupid thing with all these heatpipe boards is that they are designed to be cooled by the stock Intel cooler. That means that if you change the cooler for one that exhausts the air straight out of the case, or water even, then most of the heatpipe assembly gets no air. If this is the case then you need to stick a fan in there so that it blows across the heatsinks. Taking the assembly off now will be next to impossible due to the fact that Asus uses an epoxy type thermal material between the heatsinks and the NB/SB. When you first use the board the stuff softens and literally glues to the chipsets. I had a hard enough time removing mine and that was before the board was used. Incidentally, what case do you have this in? Does it have good airflow?

Memory Remap is for >2Gb of ram but i don't exactly know what it does. If you are using four sticks you may need to increase the NB voltage by 0.10v in the AI Overclock tuner menu.

I can't help with the FX-ll problem as i don't use mine because i have a X-Fi Extreme Gamer.

Hope this helps.

Thanks for the reply :)

The memory remap feature is supposed to allow the OS to map mem > 2gb if the mobo supports it, but winxp shows 3.5gb whether I have it on or off, so I guess I will leave it off.

I am going to definately increase the memory voltage to 2.2v when I get home, as I know that when I "undervolted" the NB to 1.25v to try and reduce the temp, the system was very unstable. However, I am loathe to increase the NB voltage as it is hot enough already!

I am using the stock intel CPU fan because I am not overclocking the CPU at all. Id just like a stable system :)

THe case I have is an old cenbro gaming bomb with a 120mm exhaust fan and a 90mm intake fan. The air flow is ok as the heat rises and the 120mm blows a lot of the heat out. However, I am considering getting a new case with side fan.
