Gamers red hot with fury over Intel Core i7-7700 temperature spikes

Some clarifications/responses

The Delid modification I mentioned in my tip is somewhat commonly done on recent Intels. Since Ivy bridge, Intel has not soldered the IHS (integrated heat spreader) to the CPU die even on their high-end chips. Instead they use regular thermal paste, the same goop you would normally use between your cooler and your CPU's IHS. (I note that nearly all AMD chips, including Ryzen, use solder.)

Dilidding a soldered CPU is only done by mad folks, imho. But these aren't soldered, so the modification is fairly safe if you know what you are doing. The IHS is held to the chip by a form of black silicone glue.

The modification on post-Ivy Intels basically involves removing the IHS (there are specific delidding tools that can be made, some use the hammer-and-vise method, others with more money than sense use razor blades.) The crappy TIM is removed and either better paste or liquid metal TIM is applied. The IHS is then replaced.

I have an i7-7700K. The K skus have an unlocked multiplier. This is a feature that's there *explicitly* for overclocking (or in my case, underclocking.) Intel even sells an enhanced warranty for K chips covering overclocking.

Even the Pentium 4 didn't behave this badly.

It's my understanding that the issue affects some non-K chips of this generation too.

Launching a web browser should not cause a 30-50C temperature spike. I probably have a particularly bad chip, but there's enough grumbling about this to suggest that there is an actual issue. The fan and pump ramping is just an added annoyance.

It's possible that this is just an antsy thermistor. I sorted the problem for now by downclocking and undervolting the Vcore and PLL and setting my cooling system to run at a fixed, tolerable speed until 60C is hit. It no longer spikes into the scary zone. I now have an antsy 6700K, basically.

Yes, gaming boards do tend to overvolt the CPU Vcore a bit out of the box. Correcting to Intel's specs did not remedy the issue for me. Indeed, this seemed to have no effect on the spikes until I also tweaked the PLL and downclocked.

To sum, here's what it took to make the spikes (or buggy thermistor) manageable:

-Delidding

-Using a fancy-pants water cooling system

-Setting voltages and clock speeds to last generation's specs

It works now and I can now fire up a web browser without fear of a meltdown.

Intel's response is quite poor given just how many people seem to have some form of this problem. I'll definitely give Ryzen a look once the kinks are ironed out.

Windows 10 Pro Anniversary Update tweaked to stop you disabling app promos

Well, the update. So, not only does it remove the GPedit toggle, it changes them back to default if they were already set.

Oh, and annoyingly, the registry key one used to be able to add to get rid of the stupid lockscreen doesn't work anymore either (though it still adds the policy message in the menu.) I suspect the others don't either.

Better still, all the bloatware I removed/disabled via powershell is back now.

Yay, progress. Here's hoping I get a minuscule class-action payout out of this.

There are already class-actions looming. Removing useful features (that may have factored into purchase decisions) like this tends to attract lawsuits and regulatory scrutiny. They've already lost/settled a few cases over the force-upgrade snafu.

I suspect these gpedit toggles won't be gone from Pro for good; and even if they are, MS will lose a lot of face and cash in the lawsuits that are sure to come. (Courts don't always enforce arbitration clauses and choice-of-law provisions like the ones that feature in the EULA; they almost never enforce max-damages provisions such as the ones that are rather amusingly there.)

See: Sony PS3 "Other OS" class-action, which recently settled.

I suspect this merger isn't going to go very smoothly...

Cameras for hacks: Idiot-proof suggestions invited

Pentax Optio WG-3.

Standard and LED flash, and pretty well priced for a ruggedized camera. I'd suggest looking over some reviews to see if the image quality is good enough for you- it's decent, but not top-end by any means. It claims to be shockproof, waterproof, coldproof and crushproof- I can vouch for everything except crushproof and coldproof.

I can further attest that it's beerproof.

The fact that it's ugly as sin may also deter thieves.

In short: It can take a beating and a dunking and is mediocre in most other things. But the lens is in the right spot (unlike many ruggedized snappers.)
