Should i look at lapping my new i7 970?

post #1 of 19
Thread Starter 
just ordered a new chip, and i was wondering if i should look into lapping it before i add it to my loop? i have a EK supreme HF which by nature is curved anyways? should i be doing this to such an expensive, brand new cpu? how much risk is involved??

Not worth the hassle with a brand new cpu! Only real risk is if your cpu decides to die one day you have voided your warranty so no RMA

Lap it when you have either of the following...
  • A newer processor than the one you plan to lap
  • void the warranty in some other way
  • do not care about warranty just that 5-10c cooler temperature
thats when you lap something.

Hey.

I would run some trials on the CPU first prior to lapping.

Lapping will void the warranty and will most likely decrease the re-sale value.

I would like to say (no offense toward Phoenixlight) that the article that was linked is steeped deeply in misinformation. The author seems to intentionally use verbiage that will lead the reader to think of lapping as a careless and thoughtless process. It is not.

There are benefits to lapping (I have lapped a number of CPU's), but I have only done so only when I felt that the potential benefits outweighed the known cons. As an example, years ago in the OCN top 20 systems, mine was the only Allendale in a sea of Conroes. I was able to get the clock speeds and load temperatures that I did due to a meticulous lapping process.

I love editorials where the author talks out his arse.

If done properly, lapping works. I've done it myself, and so have plenty of other people here on OCN and around the net in general. It does void your warranty, but technically overclocking does too, so it's not like that is a major issue to some of us. It also carries the risk of damaging the CPU if done improperly. I've heard of people shorting out their CPU, getting metallic dust in their rigs, even grinding clear through the IHS. It is a fairly risky procedure and should only be performed after quite a bit of research, with the proper materials, and only if you don't mind the potential to ruin the CPU.

With that said, I wouldn't bother on a 970. It would be an expensive replacement if you bricked it, and shaving a few degrees off the temps wouldn't be worth the risk IMO. You're already going with water cooling, so your temps should be well within spec even if you OC it (provided that you use good WC components and know what you're doing).

This artical seemed like a nice grown up rant untill i saw the way he talked to the people who opposed him >.>

I personaly wouldnt ever find the excuse to lap a CPU unless i didnt care that the cpu may get damaged, and even then if it works just fine at the temps that it gets, why bother.

I see great points from both parties, people who do it and people that are against doing it.

What it really comes down to is, are YOU willing to risk it.

I lapped 3 Pentium D's before I lapped my 860. Dropped a few degrees and leveled out the difference between the cores. The 860 was, and still is the CPU I'm using, and the best one I have.

Do the research, and try it out on some older/cheaper cpu's. If you want to do it to a 970, that's your call.
