I think 1 of my g3258 cores might be close to death

while playing assassin's creed syndicate today I got a black screen twice and figured ram or gpu since it didn't power off. Ran a memtest86+ and it passed ran firestrike demo well it didn't black screen but the score was 900 pts lower from when I last ran it maybe 6 mo ago after getting a 280x could be driver, but I ran a prime 95 test. 1 core was stuck at 1st part of test 1 while the other was already on test 2 of the second part stopped it and lowered oc by 100 mhz and .05 volts they seem to be working better and ran it for 8 hrs just to be sure no crash and stayed @ 56 c

my 3d mark test (look @ detiled scores) I tried hunting for my old score but couldn't find it
http://www.3dmark.com/fs/6562850 @ 4.2 ghz
http://www.3dmark.com/3dm/9389433 @ 4.1 ghz
my physics is just so low compared to others @4.2 ghz even 4.1 ghz is abysmal compared to stock scores

am I right or just being stupid
If 1 of my cpu cores are dying should i go with another g3258 or save to get a i5 4460

That isn't always an indication of stability as I have found out while OC'ing my CPU and some older AMD CPUs. They would be prime stable forever but certain programs would cause the OC to fail, especially games for whatever reason

Did your black screen issue go away with the driver switch?

I haven't played with that CPU so I am not sure why your physics score would be that low. I see you are running 3x DIMMs, a 4GB and 2x 2GB. Is it running in single channel mode or flex mode in your BIOS? That is the only thing I can think of off the top of my head that might cause some sort of slowdown.

The last thing I would try is removing the 4GB stick and setting up the 2 others for dual channel mode and see if that makes a difference. I don't...

http://www.3dmark.com/3dm/9394634 with cpu @4.1 ghz like I said it's the physics score not the graphics score and in prime 95 1 of the cpu worker cores would not get past the 1st phase of test 1 the 640k test while core 2 was in phase 2 test 1 the 8k test. when I lowered it by 100 mhz and .05 volts both were working but 1 core was a little slower but I have seen that before on other cpu's

btw I have looked into xeon's before but my mobo does not list it as compatible.

I don't want to recommend a new CPU because that might not be the problem. If you are set on getting a new CPU you can't go wrong with that i5. My brother has that one and he loves it. I use the 4790k but only because I do a lot of rendering and recording.

Oh yeah btw what voltage have you been using on your OC?

ok so here is what i got http://www.3dmark.com/fs/6567969 - note that it says the graphics driver is unapproved also. I was using the WHQL driver so I don't know what causes that. Anyway I don't really know what that physics score is/means. If it is a measure of multithreading then that works out to 1547 per thread. I don't know how this is measured but if that is the case then that supports your hypothesis of a core dying because most of the scores I looked at are about in the 3000 range with yours being half that.

However I do not know and it is just a wild guess about it.

Pretty sure nobody here said anything of the sort. You sure you are not in the wrong thread?

the reason your unapproved is windows 10 sadly, and I was using 1.230 @ 4.2 ghz and 1.225 @ 4.1 and I used intel burn test to get the 1.230 @ 4.2 ghz then prime 95 for stability.. i'll try the ram but I was using that with my other score that was 800 pts higher when I got the 280x that I can't find.

http://www.3dmark.com/3dm/9398067 it was stuck in single channel but still makes no sense guess assassins creed done it lol j/k probably was just a degraded performance over time being in single channel mode and overclocked another stick of ram is cheaper than a i5 4460.

Also Suzuki I know what you mean about i5 and i7 jump getting bigger but what I took at first was since you mentioned the 1231 v3 xeon was spend the extra $50 for the logical cores which i would agree with, if my motherboard supported it. might just buy the xeon in the future anyways just to try in my mobo but I would get a msi h81m p33 on the safe side to toss either chip in and give my brother the g3258 to surf the web with.
 
Yes, i5 bottleneck new open world titles, Fallout 4, Syndicate, and so on. If you play on a 60 Hz panel, should be fine, but you're losing a lot of performance, and definitely a bad idea to pair i5 with 144 Hz panel. The G3258 is a good chip, but even overclocked it won't do well in newer titles. You should upgrade if you can, only IF those extra frames MATTER to you (in this case unplayable it seems). You should not worry about a benchmark score. Play games and see if you get acceptable performance. It's extremely subjective.

However, to answer your original question, if your CPU was damaged, it wouldn't boot into Windows.

I was not worried about the benchmark scores at first I was using the benchmark to try and replicate the problem, but noticed something was off then I ran prime 95 and figured it was cpu due to how it worked in prime 95. Then I looked at my firestrike benchmark and some similar ones and saw physics so low I thought dying core not thinking about 3 dimms would put it in single channel
edit: thought I would share what the score was with the cpu @4.2 with 2 dims instead of 3 http://www.3dmark.com/3dm/9400693 so defiantly was in single
