ASUS P5B P965 + E8200 starts to have problems

[Jesus_Panella]

I recently formatted the hard drive, so I don't think it's a matter of the operating system. I'm running Memtest on it now, and there's something that surprises me. It doesn't recognize more than 4 GB, so I'm starting to suspect that a memory module is failing.

Windows 7 recognizes the 8 GB of RAM (I use the 64-bit version), although it's very likely that if the memtest gives me errors, it will reduce the RAM of this PC to 4 GB. It may have been the best thing that could have happened to that PC.

Run Memtest in two groups of 4GB to locate the module (or socket) that is failing and hopefully that is all.

In the BIOS there is an option called "Memory remapping". If you put in 4 or more GB, you have to have it enabled for the system to detect all the memory.

It seems like there was some luck in the end.

I took out two memory modules reducing the amount of RAM to 4 GB by removing module 2 and module 4 to benefit from Dual Channel, and it seems that the values that were always giving me have been reset.

I tested the super pi and it's back to the 17 seconds and a bit that it used to give me, just like the graphics card is back to the values it used to give both in benchmarks and in games, before that problem occurred.

In the Windows 7 evaluation test, the scores have also been reset, since with 8 GB of RAM, the memory was only indicating 5.5 points, worse than even the hard drive, which gives 5.9. After reducing the RAM to 4 GB, leaving it in Dual Channel now it's indicating 6.3.

It's hard to believe what can happen to the computer if a memory module is broken.

Don't rush, because it could be a matter of one or several memory slots and not the modules themselves, as Nemo said.
I would change the 4Gb that it has right now for the other 4Gb that you removed from it, using the same slots and see what results you get, because you might get the same performance again and the modules are perfectly fine and it's a matter of the motherboard. Make sure of that.

I've tried the other two memory modules and after running the tests, they indicated that they were fine (no errors) and practically gave the same results in all the tests.

However, I changed the position of the memory modules by putting them in banks 2 and 4 and it seems that I'm seeing a strong slowdown when posting and when loading Windows (it takes me fifty percent longer, despite having recently formatted it). However, the super pi 1M test still indicated 17 seconds and a few tenths.

The 3DMark Vantage gave practically the same result (10,350 points), but in the 3DMark06 the score dropped by more than a thousand points, going from getting 12,500 points to only 11,000.

Is it really the motherboard that is having problems?

I opened the tower and observed that everything seems to be correct, but in the last tests I heard a strange little noise coming from the motherboard that I didn't like at all. <:(

It should be taken into account that I have been using this PC for four years very intensively and in fact I am still using it very intensively despite the fact that it is no longer my most powerful PC. Moreover, I am using this PC much more intensively than my main PC (the Core i5 2500K) which I use for programming and playing some games at night. But I play many more hours with the Core 2 Duo, due to the fact that it is connected to the internet by cable and not the i5 2500K (which is connected by Wifi).

In addition, this PC even survived a voltage surge that took out its first power supply and probably between this and the fact that I am using it very intensively, this may be causing the motherboard to be aging.

So that's what I suspected, that it's the slots or one of them in particular that have problems. You can try giving it a reset/flash of the BIOS and maybe it will work again and pull well with the 8Gb, some motherboard has already done this to me...

Well it seems that the culprit is the ram socket that for any failure might not supply enough voltage or whatever.
It sometimes happens that the connectors get dirty or simply some solder that loses effectiveness. But it can happen to all connectors, PCI's, USB, ram sockets... suddenly one day they stop working.

Isolate the one that gives you the error, if only out of curiosity, because I'm not sure if it's a good idea to put 3 ram modules in it or maybe if it compensates.

Good afternoon again. After doing several revisions, I realized that the memory socket that was failing was the 2. That's why when I put the memos in the 2 and in the 4 I was going slower than in the 1 and 3. I also tried doing 1, 2 and 3, and I got errors again, while 1, 3 and 4 didn't give me errors. However, with three memory modules (6 GB of RAM) I saw that it was not a good idea, since it canceled the Dual Channel and slightly lowered the results. I decided to do a total cleaning of the motherboard, socket by socket, noting that the memory sockets were the dirtiest, especially the one that was failing, noting that sockets 2 and 4 were the dirtiest. Previously this PC had 3 GB of RAM (one of the memory cards was 2 GB and the other 1 GB) and the memories were placed in sockets 1 and 3. That's why sockets 1 and 3 were cleaner than 2 and 4. Then it was when I replaced the 1 GB memory that had socket 3 with a 2 GB one, having the PC with 4 GB and benefiting from Dual Channel, increasing its performance considerably. Upgrading the PC from 4 GB to 8 GB of RAM I barely noticed improvement as at first I imagined I would notice at the beginning, when socket 2 still didn't fail. After cleaning, socket 2 works well again, after doing the tests, and I tried again with the 8 GB of RAM. However, the results it gave me in the benchmarks were practically identical to those with 4 GB of RAM, except for a slight improvement in the 3DMark06, and the fact that in the evaluation of Windows 7 it gave me 6.6 points when with 4 GB it gave 6.3 points. Seeing the very scarce difference in performance in having that PC with 4 GB that with 8 GB, perhaps I should leave the PC with 4 GB of RAM, which was when this PC was going the best.

I'm glad that in the end it was nothing, as I told you before, that happens to many connections.
As for the upgrade from 4 to 8 GB, it's relative. If the programs you use regularly are not very demanding and the RAM usage rarely exceeds 3 GB, it's absurd to put 8 GB (just the other day I was talking about this with Bm4n in another thread), it won't be noticeable because those extra gigabytes are simply not used. It's different to go from 2 GB to 4, since Windows 7 almost consumes those 2 GB without starting any program and you can notice an improvement in performance.
However, if you really use programs that exceed 3 GB or more in consumption, its expansion becomes essential.

Best regards

I agree with Nemo. For example, I would need more memory because I use VST instruments to produce virtually and so on, so I usually have to load large amounts of samples and applications into RAM, and it is noticeable with only 3Gb. Since you have 8Gb, leave them placed, if you do not notice any slowdown or problem, better 8 than 4, and if you are going to virtualize even better. If on the other hand you are not going to use it, you could save them or sell them, whichever is more practical for you.
