Search around...read...then ask me anything you don't understand.

Thanks.

@kalabok -

If I say I have posted information to this forum previously concering the topic at hand, you should be able to find that using the Forum Search feature.

In this case, since the topic is UC/UW...just search for that, MTRR, or LFB...and voila!

Since you have posted here previously that you are overclocking, I would expect that you already have more than a basic knowledge of the K6 CPU and its features...because you should have this knowledge before you ever attempt to exceed the design criteria of a particular component.

I personally don't like repeating myself over and over again (spoon feeding)....nor should I have to do it for your convenience. I don't call this being rude or impolite...it's just how I work all of the technical forums that I post to. I'm sorry if this comes off as such to you.

On the other hand, if you ask me an intelligent question because you don't understand something, I will answer it the best that I can.

Thanks.

i do not have a problem if you dont wanna repeat yourself twice. my problem is the way you are telling that to forum members. its some kind of arrogance, you know?

i am sure that you are one who knows the most of the topics we are dealing with. not everybody got a technical education like u, sometimes peaple do ask stupid questions. you cant expect peaple having same basics you have, there are noobs, peaple like "i think i know something" and experts. but the goal of k6plus is about sharing knowledge, thats why we are here.

posting a link to the propriate site needs only some seconds of time. without repeating yourself.

i would say - forum members have got zero knowledge but infinte intelligence. and it would be more adorable if all would treat each other with more respect.

ur welcome

Once again...I don't see it as being arrogant at all.

In order to post a link, I'd have to search for it myself (as I do not have a photographic memory). So by doing this, I have basically done the work for you...which I have already stated that I will not do (every time).

Hopefully this makes sense to you.

If you'll note, I did however provide you with three valid search terms in my previous post (hint hint). :wink:

There was once a time when I knew nothing about the PC. I learned most of what I know by doing my own research, then asking questions for things I did not understand. By asking the right (and intelligent) questions, I was able to attract those with a real knowledge of the subject matter...which made for a positive learning experience...and a willingness to help on their part. Having an electronics background surely made that easier...but it isn't absolutely necessary.

Jumping back to Cthulhu8u's last post...I never got to answer that. :oops:

Depending on your PC, this could be a BIOS function. Most likely though, you will need to use software to turn these CPU functions on.

Thanks.

Here's an old article regarding the performance features of the CXT core K6 CPU's:

http://www.aceshardware.com/read.jsp?id=15000166

I use Rawpower to setup Write Combining on Win9x machines that don't have BIOS support for this. In my opinion the performance gain with Write Combining enabled is negligable. Write Allocation is the most important feature you need to have enabled. 95% of socket 7 boards enable Write Allocation by default but I've run into a few boards that won't enable this.

Thanks for the link to the informative article Uranium235! :D

The question here was not about overall system performance, but strictly video performance.

As an example, here is some info from my present card -

I've been running various video benchmark applications for the last week using different memory ranges & Write Combining settings with no noticable performance increase. This was done with a Radeon 8500. Maybe this card doesn't take advantage of Write Combining? I'm going to try a different video card to see if my results are any different.

@Uranium235 -

Are you using the correct memory ranges?
