K. I was thinking if she comes up with the money, maybe I'd look into the M.2 type drives. They look pretty amazing. I know some of the boards support the interface but are really just using a SATA 6 controller so you don't get the speeds.

M.2 is a multi-type connector (PCI-E, SATA). If they just wire the sata from the ICH, thats probably going to be the fastest you are going to get, instead of using a SATA chip -> PCI-E -> ICH. This is the reason for Esata I recommend using a bracket that just plugs two esata ports to onboard SATA ports

775 was the last Intel to use FSB.

... And long term, it's not the heat that kills it, it's the high voltage that does

Both, actually. The usual failure mode is due to electromigration in the metal layers, followed eventually by a metal line fusing open or closed. All these are accelerated by high temperatures (exponentially, since it's similar to an Arrhenius process). High voltage increases the power dissipation of the chip (quadratically), causing the high temperatures. Overclocking adds a double-whammy, since higher gate-switching frequencies cause a linear increase in power dissipation in CMOS with frequency.

Conversely, undervolting and underclocking gives huge improvements in lifetimes of processors, though in practice the difference between 100 years and 100 million years is irrelevant - processors are obsoleted in 9-month or lower refresh cycles. Nevertheless, I'm still running my Wolfdale X5260 Xeon (3.3 Ghz with 1333 FSB) underclocked to 2.83 Ghz/1066 MHz FSB and undervolted Vcore of 0.95V max. Runs cools as cucumber (a few degrees above ambient) with generic Intel S775 coolers. The X5260 is a S771 Xeon to which I've installed the 771-to-775 conversion sticker mod. The same can also be done to quad-core S771 Xeons (sticker mod, underclocking, undervolting).

Hey, don't a lot of the motherboards overclock the RAM? I'll see stuff like this:

DDR4 3300(O.C.)/3000(O.C.)/2800(O.C.)/2666(O.C.)/2400(O.C.)/2133 MHz Non-ECC, Un-buffered Memory 
Quad Channel Memory Architecture

If I bought something like a couple sticks of DDR4 3300 MHz RAM, and popped it into something like the Asus Rampage V Extreme, would the motherboard just automatically configure itself to run the RAM at the higher speeds? Or generally when they list the RAM speeds with the (O.C.) part, does the user have to specifically set the settings?

actually its whether the ram wants to be overclocked or not according to the spd data in the ram modules which tells the mobo which speeds and timings the ram module supports.

some overclocked ram modules also contain sumthing called xmp profiles which are overclocked speed & timing settings. if the mobo supports xmp profiles, u can tell the mobo which xmp profile of the ram module to use on boot and the mobo will "remember" it until u change ram modules.

Seems like 2133 MHz is the only RAM speed they support that doesn't need overclocking.

2133mhz is the intel specified standard default officially supported ddr4 memory speeds supported by the imc inside skylake cpus. whether those overclocked speeds will work or not depends on the asic quality of the imc inside the cpu. if the imc cant handle the speed demon ram speed of 3.3ghz, it will auto downclock to the next lowest until the system can post but then u might have wasted a lot of money on the super high speed 3.3ghz ram...

Thank you Uranium-235. I was going to go for the M-key type M.2 ones. The ones that connect directly to 4 PCI-E lanes. From what I've read, that'd be the fastest because it's the only one that delivers four PCIe lanes. Unless I'm misunderstanding something.

I'm familiar a little bit with the XMP profiles. When I buy RAM for a system, I tend to try to stick with what's listed in the QVLs because a lot of times, if the RAM I buy doesn't work, the manufacturer usually asks if it's listed in the Qualified Vendors List and if it isn't, they tend not to be too helpful. Now, with RAM that's listed as 3300MHz, do the actual sticks need to be overclocked to get that speed? Are they really 3300MHz or is it just that you can overclock them to 3300MHz?

I'm just a little confused on the RAM stuff here. In the BIOS, if the board supports 3300MHz (O.C.), that'd mean either I or the motherboard would need to increase the voltages and stuff going to the RAM and maybe play with the timings a bit, right? I'm just curious if the RAM that's advertised as 3300MHz are really something a little slower that's guaranteed to work in certain motherboards when overclocked or if they're actually 3300MHz.

XMP does specify voltages. Your motherboards overclocking software in the bios should adjust it if it supports XMP

Re: Difference between socket 1156 vs 2011.

So does that mean RAM that's listed as 3300MHz is actually 3300MHz or does it mean it's designed to be overclocked and will run at 3300MHz when overclocked?

[Uranium-235]

Re: Difference between socket 1156 vs 2011.

if the motherboard fully supports XMP and you have a system with a good memory VRM, it *should* work. If the board is designed for 3300 and the memory is designed for 3300, it *should* work

im just going to point out here that some types of overclocking ram designed to run at higher speeds are actually lower speed models that the manufacturer found perform better than expected during testing/binning and were thus "promoted" to be sold as high speed overclocking ram rather than value ram.

one example that i know of some time ago are the kingston ddr2 hyperx ram modules. the ddr2-800 hyperx modules are actually ddr2-667 ram that were found to be able to run at ddr2-800 low latency 4-4-4-12 speeds. likewise for the ddr2-1066 hyperx modules. they are actually ddr2-800 rams that the manufacturer found was able to run at ddr2-1066 5-5-5-15 speeds.

so the 3.3ghz ddr4 ram could be ram that is manufactured as 2400mhz or any other lower speed than 3.3ghz modules but the manufacturer found them to be able to reach 3.3ghz during testing/binning and so sold them as such at a higher price to increase profits.

Re: Difference between socket 1156 vs 2011.

Thanks ChaosLegionnaire! That answers my question for sure! Is there any way to tell if it's really a slower chip that's just advertised as being a faster speed because it runs stable when it's overclocked? I know that they'd just change the profile on the sticks so I'd probably never notice they're being overclocked...

Re: Difference between socket 1156 vs 2011.

no, no easy way to do that. not without voiding the warranty. u see nearly all overclocking ram modules have heatspreaders on them. this obfuscates what ram ICs are being used on the modules and dismantling the heatspreaders voids the warranty.

one way is to just look at reviews of the ram u are buying. some reviewers may pry off the heatspreaders to see what ram ICs are being used but not all reviewers do that. thats also assuming the manufacturer is honest and didnt pull a "bait and switch" by sending to reviewers different stuff than what is actually being put up for sale.

so unfortunately, there is no easy way to "check out" a ram module and see what it has under that skirt errr heatspreader... lol

Thanks. Kinda sneaky of them I'd think. If you're buying something like a 1333MHz stick, you'd probably expect that you could overclock it a bit. If it's already overclocked though, I'd think you wouldn't be able to go much higher, not stable at least.

[ChaosLegionnaire]

Re: Difference between socket 1156 vs 2011.

well, i had the kingston hyperx ddr2-800 and i found that it overclocks just like the ddr2-1066 hyperx. tested in memtest and prime95 blend for hours in a 4 stick config together with the hyperx 1066. no errors. never had a freeze or any ram related issues in normal and gaming use.

so if u're lucky and buy from a reliable and good brand of ram, u may end up lucky and get more than what u paid for...

After watching this https://www.youtube.com/watch?v=dWgzA2C61z4 it seems that speed isn't so important.

[Spork Schivago]

Re: Difference between socket 1156 vs 2011.

Thanks Diif! That explains why I couldn't find high speed RAM with low latency! The guy says in order to get the higher speeds, they need to loosen the latency a bit and when they tighten down the latency, the speeds drop. Hence the reason the higher speeds tend to be around the same as the lower speeds. High speed, high latency, lower speeds, lower latency. I know with my wife's laptop, I was looking to upgrade her RAM and I couldn't believe it! To max it out, the latency was something like 11! I remember when the RAM for my old desktop, I had something around 4.

Re: Difference between socket 1156 vs 2011.

Quick question though. With video games, he's testing how fast the RAM is actually working by FPS in a game. Is that a valid test though? Doesn't the video card have a lot to do with FPS? The RAM on the card, etc...

Am I wrong in this or is he basically saying something equivalent to I put 86 octane in my car, the AC temperature goes down to 65 degrees F. I put 93 octane in my car, the AC temperature really doesn't go any further down, it stays at 64.9 degrees F. Therefore, lower octane is just as good as higher octane...

Re: Difference between socket 1156 vs 2011.

I think was he was saying is that expensive faster RAM doesn't make much difference to FPS or real world performance in applications.

Yes, you are correct, the choice of graphics card will have more of an influence on FPS than the speed of the memory.
