Funny CPUID screenie

[DaGooch]

OP did you notice the one guy above you on VR-Zone, his SSE is not functioning with the same version of CPUid? I noticed more than half of the guys on the first page have junk screenies with 64K of L2 or their SSE not functioning.

[OPPAINTER]

Yea a bunch of sh*t, they look all messed up, to cold I guess, at least mines official:D

[DaGooch]

Yes, only yours and several others are the only 100% fully functional XP screenies.

[OPPAINTER]

Thats all right, I get one these 2200 chips and I'll snag the lead with a 2300 Screen Shot.

you think these guys are faking their results? Not on losing the L2 but rather the fubared SSE2?

What are L2 and SSE

[stompah]

most CPUs (all currently manufactured) have onboard memory which is basically called a cache. It helps the CPU in most cases.

For SSE2 its some instruction that is on the chip that enables the CPU to 'pre-fetch' information from the memory before it needs it. Basically it is prediction the future based on your habits ;) I think I am not 100% certain on this one.

So what was diff about those guys CPUID?

So what was diff about those guys CPUID? Their CPUs are super cooled. Cooled below freezing often times. And that creates some funny stuff happening n their CPUs. Athlons XP have a 256kb L2 cache and they also have SSE2. What is likely showingup is 64kb of L2 cache and/or SSE2 not enabled.

One of these days I will understand this stuff, I,m getting there.;)

Don,t worry about it, I always get 2 or 3 points of view before I act.:D

Identified as a "Duron" with 64K of L2 cache and no SSE and some have 256K of L2 cache showing but no SSE instruction set which is present on an Athlon XP.

[JCviggen]

Yeah those screenies where the CPU is barely running with stripped cache shouldnt count.... anyway I submitted one once without realising i had lost the cache but they refused to publish it anyway... but there's still plenty of entries up there with the same prob

[Sayajin]

Athlon XP cpu's do not have SSE2 they onlt have SSE...SSE2 are the instructions used in P4 cpu's...intel has givin AMD a licence to use SSE2 in their cpu's...but only in 2003...

my computr science professor said that since the l2 cache doesnt run as hot as the rest of the chip if you freeze it enough part of it can fail to turn on bc the gates actually freeze on some of the transistors then he proceeded to show us what happens when u blow out the l2 cache with to much vcore lol

[Bulldog]

Now thats a kewl professor...how many volts dis he try to run thru it? This is one course that you should get a super grade in...maybe some extra credit by teaching him how to clock:toast:

[KnightElite]

Yeah, SSE2 is only on P4s and Xeons for now. Hammer will have it though. Athlon XPs have 3DNOW! and SSE and MMX instruction sets. All of these are SIMD instructions, which stands for "Single Input Multiple Data." Basically, they are a bunch of pre-made calculations that make it much faster for the CPU to do certain operations.

you da man go do it

Hardass, if you want to learn about how CPUs work, I'd advise you to stay away from this forum.

"For SSE2 its some instruction that is on the chip that enables the CPU to 'pre-fetch' information from the memory before it needs it. Basically it is prediction the future based on your habits I think I am not 100% certain on this one."

-No. SSE2 (Streaming SIMD Extensions 2) is not prefetch. Prefetch circuitry and SSE2 are different. Also, prefetch does not make predictions based on your habits.

"my computr science professor said that since the l2 cache doesnt run as hot as the rest of the chip if you freeze it enough part of it can fail to turn on bc the gates actually freeze on some of the transistors..."

-Your professor is an idiot. Find a student who records the lectures, take the recording of that lecture to the head of the department, and demand a refund.

"All of these are SIMD instructions, which stands for "Single Input Multiple Data." Basically, they are a bunch of pre-made calculations that make it much faster for the CPU to do certain operations."

-Partial credit. SIMD stands for Single Instruction Multiple Data. SIMD extensions are not pre-made calculations. SIMD extensions allow the processor to perform a single SSE instruction on multiple data in one shot instead of doing the same operation over and over again.

"most CPUs (all currently manufactured) have onboard memory which is basically called a cache. It helps the CPU in most cases. "

-This isn't so much wrong as it is dumb sounding. The onboard memory is not basically called a cache, it IS called a cache. Cache is very fast SRAM (usually) that stores data and instructions and acts as a buffer against the horrible delay of fetching data or instructions from the system memory or (even worse) the hard drive.

I'm not trying to hurt anybody's feelings, I'm just fighting the good fight and spreading the message that it is okay to say "I don't know" if you don't know what you're talking about.

[Hardass]

Locoman, Thanks for looking out for my well being. But have to tell you this, In a short period of time at this forum I have learned more then I did the entire time at other forums. So I have to take my chances here. Can,t let the statements of one or two people change your view of the overall picture my friend.:toast:

[JBELL]

ROTFLMAO

[Locoman]

Yeah, you're right. Ignorance is bliss. Seeking the truth and doing real research is too hard.

Let me guess, you're a product of the US school system, right?

[Locoman]

removed

[Hardass]

Hey man you need to chill out with the attitude, don,t know what your problem is but you made your statement now let it go.

Do we need to have a chat?


cool out or get out

[Locoman]

But all the fun of trolling is copping an attitude and not letting it go!

Okay, I hear you. I'll leave you alone now.

you don't seem to understand I do NOT allow flamming here, you wanna talk smack and cop a 'tude then go somew[H]ere else besides here.
