So to kick things off ear, im going to start with a small timeline of events so you guys more easily understand my situation.

A few days ago I added a 240 gb PNY SSD to my rig (550 read 520 write) and upgraded my ram from 8gb of gskill to 16 gb of corsair ram THE DAY AFTER I got the SSD. For a day or two, everything was fine. I was loading into World of Warships games 45 seconds before the round started, not 15 seconds after; basically I was noticing massive difference in old ram and hdd compared to new ram and ssd.

Then I began getting a lot of BSOD errors. Didnt know why. Ended up running Memtest and got tens of thousands of errors. I RMA'd both sticks and got them replaced with the same model.

The new ram got through memtest with no errors. However, my load times in games are more like when I had the old ram and the game was on the HDD. The benefit of a 80$ ssd and $110 ram seemed to have disappeared. The ram passes memtest, and crystal disk got about 440mb/s read/write. Now i am upset that it is not at 550 as advertised, but I shouldnt be having load times like my old HDD.

I decided to use IntelBurnTest to stress test my CPU. As of now, the first test yielded stable results, however I committed more ram and am running it again. Here is the new problem I discovered; my temps are fluctuating like CRAZY. Im using a Corsair h100i with the stock fans it came with. Ive seen the temps go fron 76 degrees celcius to 103 degrees celcius when under stress.

Given that the RAM and SSD are passing stress tests as well as the CPU, is it possible I may have messed up the h100i when installing the new hardware and the high temps is causing the slow load times? Ive also seen Task Manager say the cpu is under 100% load even when all programs running total at 50% or so. I have no malware, already tested that, and the pc has been dusted.

EDIT: The second cpu test gave stable results as well, but the second it ended the temps dropped back down to 45 degrees celcius? Does it not take any time for these things to cool off???

Its very possible that your cpu is throttling, have you tried taking off the cooler and reapplying thermal paste then reseating it? Also what is your 4690K clocked at and voltage used?

Also to answer your question about thermal throttling, its when your cpu (or whatever is overheating) clocks way back to prevent itself from overheating. For example, when i had my 4690K clocked at 4.4GHz i got temps up around 103-107 on IBT and Prime95. Looking at cpu-z the clocks dropped way down to like 800MHz on the cpu to cool it down.

Intel burn test is pretty intensive. Is the cpu overclocked or at stock? If it's overclocked did you do so manually through the bios or pick a preset performance option from the bios or oc through software?

The reason your cpu dropped down to 45c after hitting 103c during the test is likely thermal throttling. If in fact you're hitting 103c stop testing with ibt, that's far too hot. Did you check to see if you felt hot air blowing from the radiator? Did the fans spin up noticeably faster on the radiator? If you meant that the cpu dropped down to 45c once the test was over that's normal. It's not like a big bar of iron or steel that retains heat for a long period of time, temps rise and fall within seconds.

On the crystal disk read/write, were they the sequential? I'm guessing you're referring to the pny cs1311 (you didn't specify, different models may make a difference). The advertised read/write seemed to match what you said yours was. The reason I ask, review sites have tested it using crystaldiskmark 3.0 (version is important, if yours is different results can't be compared necessarily). They got seq read of 552mb/s and seq write of 529mb/s but those numbers dropped on 512k read to 434mb/s and 512k write to 519mb/s.

Ssdreview did testing on several drives and in spite of synthetic benchmarks, they did real world data transfer from one ssd to another. The pny cs1311's they tested were the 120gb and 480gb, suffice to say the 240gb performance likely lands somewhere in the middle. It's common with ssd's for performance to get a bump with drive capacity. Here's the results of a 30gb transfer.

A value somewhere in between the 120gb and 480gb versions coincides with the sort of data transfer from a wd blue 1tb 7200rpm. There's another model, the cs2211 which performs better. Depending how full the drive is, performance may or may not have dropped some. I'm also assuming you loaded the game onto the ssd and it's not still being read from the hdd?

Yes it is the CS1311, and i used crystal disk 5.x. I did not feel the air coming out of the radiator. And what exactly is thermal throttling? Is there a difference between that and the actual temp of the cpu?
