Geforce GTX 280 Advice Please?

[jigger]

So you are an electronics expert ?

 

[jigger]

You really don't want to go into it... its a long - semi complicated - and not very interesting story.

Short version: if you really want to be pedantic about the expert bit I have the qualifications on paper that says so (A grade double science GCSE with physics/electronics extra modules, A level and higher qualifications in physics and electronics, etc.) the truth is I'm not that good at it being out of practise never really putting what I learnt into use since leaving education almost 10 years ago. But my dad is technical manager for R&D at a well known UK company so we have all the hardware here at home (yes I'm living with my parents).

Your dad just happens to be in the same line of work and you have the testing kit at home ?

 

[Rroff]

It just so happens... your taking it completely out of context tho... I just happen to have tested my GTX260 setups awhile back out of interest when someone brought up the topic of 200 series power consumption - as we have the hardware here (we also have electron microscopes and goodness knows what else) - so chipped in here because those graphs are not representative of the figures I have from testing 4x GTX260.

 

[jigger]

You tested the four gtx260's in person (with Dad ) and at Idle found them to use 4 watts less than what Techpowerup did ?

You really have electron microscopes at home ?

You really have electron microscopes at home ?

We had 1, not sure if its still setup here - this is the sorta stuff my dad does: http://www.boliven.com/patent/US6685746

 

[jigger]

So you tested ?

Take your time...

 

[Rroff]

whatever

 

[jigger]

I'm tempted to call those graphs inaccurate tbh... I'm yet to find a GTX260 (and I've a fair amount of experience with them) that idles around 30+ watt - highest I've seen so far is 27 (most are 25-26).

I have no idea on 5850 v 280 - I just know from extensive experience with the GTX260 that its unlikely to draw 31watt idle - which to my mind throws question on the rest of his figures.

You don't need a sophisticated device, a simple adapter (and knowing where to measure) and a DMM is more than accurate enough for GPU monitoring.

 

[jigger]

You don't need super accurate monitoring gear to measure the power draw from the pci-e socket and additional connectors to well within the accuracy of a watt - even cheapy off the sheld gear is probably correct for calculating within probably 1/100th of watt which is more than enough for this purpose.

nm

EDIT: Anyhow thats arbitary to my point. My own measurements are properly done and not with a cheapy device anyhow.

I edited my post, I didn't use a cheapy method anyhow in my own testing - I was just saying that even cheapy equipment is more than capable of accurate enough measurements for GPU purposes.

To say TPU is "unbias" is a joke.

Maybe.

 

[Rroff]

If I thought you were actually seriously looking for an answer I'd give you one but I know thats not why your asking the question. I get it you don't like me go bother someone else for a change.


EDIT: LOL get a GRIP starting to wonder if I'm gonna need a restraining order your obsession with me is becoming a little too weird.

 

[REAPERUK]

LoL you don't know how wrong you are, everyone on this forum who reads your posts know how wrong you are too. Regarding this thread, when I see someone posting clear misinformation, I will correct them.

OT, 280 for £120 is about right, I wouldn't pay anymore for one though.

so the above hardop test is lies? you need tobe a user before educating people.. i find you lack of faith disturbing lol. one thing i will never learn from your posts on here, and that is a fact..

nice edit though..

You do know that the hardocp figures you quoted are total system power readings right? The GTX 280 is on a core 2 quad and the 5850 is on i7.

1-core 2-core 4-core, does not matter, the Gpu takes what ever power no matter what pc spec.. you add load on any system to the gpu it takes power.. no matter what platform, this is were fanboys hate truth most.

Rroff you can post how to tie show laces Guide, but you will still get a Discussion on that, it is hard to educated the Blinkered individuals who just reads reviews,but this is inevitable imop

Read the thread back to yourself slowly. I don't no why you keep doing this but your killing me with this crap.

 

[Rroff]

lol well I'm sorry it kills you and I might have got a bit carried away with the cheap testing crap... but nothing I've said is actually untrue; I do happen to have qualifications in electronics even tho I would not call myself an expert by a long stretch, I have tested multiple GTX260 idle/load power useage and found it to be well below that posted in the TPU graphics and my dad is bang on your stereo typical scientist and has the patents to prove it (which is why I have the testing hardware).

 

[jigger]

Your story is simply unbelievable Rroff.

what type of electron microscopes do you have ?
Go and have a look if you don't know but considering your level of "expertise" you should know.

Why did you use a cheap power monitoring device when you just so happen to have qualified testing equipment and a skilled family member to hand ?
It's even stranger you never used the test kit considering "you used the test equipment" just "to chip in" on a thread when gt200 power usage come up.

Can you link to that thread ?

Why in your first post did you not give detailed information about the kind of testing you did and seemed to be struggling (avoiding all technical questions Editing posts ) to give a straight answer ?

Just what what qualifications do you have ?

Why have you edited your posts to suit the argument ?

Why did you attack people for asking questions ? You come up with this fantastical story not me. I simply wanted to know why I should take your *OPINION* over an EXPERTS.

And why do you start crying/getting personal when you get called out after posting this pointless drivel ?

Gtx 280 for £120.00 is a bargain, who cares about power draw, im sure most of us here pay our own leccy bills. I used to run a single gtx 280, awesome card, when it sadly failed i got a gtx 275 as a replacement, (not a great deal i thought) but i stuck with it, bought a second identical 275 gtx on MM, cheaper than a 5850 which only offers mediocre DX11 features and terrible driver support, i know nvidia drivers arent perfect either, but ive never had any serious issues with nvidia.

 

[Rroff]

We both know your not actually after a straight answer.

Its not something I just tested recently - it was months back - and I only did it out of casual interest because someone was asking about power consumption of 200 series cards. I can't even remember if I posted in the thread or not. Theres nothing to testing really aslong as you have a setup that can handle the amperage - couple of jury made adapters to monitor the 6pin inputs and the PCI-e slot power blade.


EDIT: I've just seen why his "idle" figures are higher than mine:

"Idle: Windows Vista Aero sitting at the desktop"

I was testing on XP with just a plain unaccelerated UI - using aero is going to increase power useage slightly.

A while back Rroff, big wayne posted up a graph from a review about power consumption of cards, i was interested in the sli gtx 275 results, 599w at full system load, unfortunately he didnt post up what cpu they were ran under, id like to test my own sli gtx 275, 4ghz i7 setup, psu is a corsair HX850w.I imagine the gtx 260's are similair in power draw to the 275's.

We both know you can't give any because you made it all up.
